Weight of the load of raw material varied between 10 and 21-t. Values obtained on the material equilibrium are given in Table 2. Data in Table 3 showsthat the properties of coke are not so dependent on the nature of the raw material as on the conditions of preparation. During the cokin of petroleum pitch about 40% of distillate is obtained. qhis distillate has a high specific weightp a high naphthalene content and a high coking number. The percentage composition of the coke distillate is given. It was fractionated in a 6 m column (35 plates) and was found to contain 13.9% hydrocarbons(~oil~nr between 790 and 2050C),- a benzene - fra8tion and 16.9 ofa fraction boiling between 2100 and 330 C. The contpnt of sulphonating compounds in the benzene fraction having an iodine number of 103 and a molecular weierht of 113 = 62%. The content of aromatic h rocarbons was defined according to the GrozN11 method ( ef.2) and did not exceed 16.5,%.

The author offers theoretical material for development of standards of sealing collars for rotating shafts and of sealing rings for cylinders and rods. Equations and calculation ex- amples are given for specific pressure of the rubber collar on the shaft in the case of rubber alone and in the case of brace- let springs(Fig. 2) employed in the collar design, as well as for calculation of heat balance and friction. The author con- siders the sealing rings enclosed in metal cases - used in the machine tool industry - as being unduly complex and having no technical advantages, and recommends instead the simple de'sign of collars without reinforcing metal rings (Fig. 3) as are used by the machine tool plant imeni Ordzhonikidze and plants of inner-grinding machine tools. The machine tool plant "Krasnyy Proletariy'i uses similar rubber collars with a rein- Card 112 forced metal ring (Fig. 4). The metal ring is designed to pre- Standardization of Rubber Sealing Gaskets in Hydraulic Devices 28-3-7/33 vent the "secondary" shrinking of rubber, but large diameter metal rings get distorted after stamping, and this affects the shape and tightness of sealing ring gaskets. The article also contains data on allowances and tolerances used at the plant imeni Ordzhonikidze and on technical conditions for the.rubber grades A-1 and A-2 employed for these sealing devices. It is stated that rubber rings have replaced the former cast iron rings in many applications. It was established by laboratory experiments that sealing rings made of rubber A-2 did not show any noticeable wear after 350,000 double actions at 35 atmospheres pressure in the cylinder.

The normalization of small tools with nominal diameter less than 1 mm, which st'arted only recently, becomes important in view of the development of the watch and instrument industries. The article makes a review of the present status and gives the numbers of the related rOCT Dimensions and tolerances for metric thread of the I and II accuracy classes for diameters of 0.3 - 0.9 were standardized in 1946 ( roCT 3196-46, 3197-46 and 3198-46). Fits and tole- rances for smooth work of less than 1 mm diameter were stand- ardized in 1954 ( rOCT 3047-54). roCT 6636-53, which estab- lished the number series for selection of linear dimensions and diameters, served as the starting point for the new stand- arde for drills and reamers - rOCT 8032-56, 8034-56 and Card l/ 2 8035-56, developed in 1956. Standardization of Minute Tools 28-4-8/35 Detailed information is given on these latter standards including the principles of construction (the preference series numbers and denominators), 4 dimension charts and one drawing of reamers. The standardized tool assortment is said to meet all the,needs of the watch and instrument industries. The author considers it sensible that the technological norms recommended with the issued standards be regulated by branch norms or standards, in which the geometric progression should be followed not only for diameters but also for other values such as the length of the work portion and the overall length of tool. There are 4 tables and 1 drawing.

The article gives the theoretical foun- dation of the project for standard series of small (under I mm) modulesp which will have to form the basis for a chain of standards and norms. The principles of the proposed series are explained in detail and accompanied by related computations, tables and diagrams. The difference between this proposed series and the series proposed by the International Standard Organization's Technical Committee No 60 is pointed out. The module system of the Moskva Tool Plant (MoskovPkiy instrumen- tallnyy zavod), with 11 modules, Is mentioned as typical for the entire Soviet instrument industry, since this plant pro- Card 1/2 duces all the gear cutting tools.

The space between the teeth is correlated with the length of the broached opening, which, in turnhas a functional correlation with ";,he diameter of thevopening. Thus, before establishing a series of spacings, it is necessary to fix the series of diameters and lengths of the broached open- ings. Since the spacing series must correspond to a geo- metrical progression, the other two series will also form such progressions. The author computes analytically the Card 1/2 interdependence between the series.

High-speed steel must now be used where the temperature of processing may attain 6000C, and cobalt high-speed steel where it attains 6500C, Particularly important is the approval of EOCT 9373-6o (GOST 9373-60) which includes nine instead of four typee of high-speed steel. 80-90% of all cuttinj; tools are hard alloy. The VNII worked out standards for various types of milling tools, hard- alloy drillsp and round files. The geometrical parameters of the cutting Card 1/2 Increase in Quality of Metal-cutting Toole B102616010001061051028 B012/BC05 elements are also important for the service life of tools. The old standards were canceled and considerably altered. Instructions con- cerning the geometry of cutting tools are being worked out at present, They have been published for drills, awls, reamers, and taps. The in- fluence of inexact teeth is noticeable in conical; cylindrical, and spur-gear cutters, but only under heavy load, It was specified in the V standards for ooarse-tooth cutters. An increase in the slope angle of the metal-cutting groove from 25 to 4W6 has a favorable effect on the vibration resistance. The VNII examined a number of standards concern- ing the vibration resistance in the system workbench - workpiece - tool. With respect to the accuracy of tools, the tolerances for awls and reamers were fixed. The standard on tolerances for gear wheels contain- ing nine instead of four ranges of accuracy was published in 1956. The VNII also coordinated the standards for worm cutters and planing tools with the standards for gear wheels. Card 2/2 VAKSMAN, AN. ----------- Standardization of metal-cutting tools.

(Ratsionalizatsiya szhiganiya antratsitovogo shtyba na Minskoy 7ETS-3) PERIODICAL: Toploenergetika, 1058, No.3. pp.26-28 (USSR) ABSTRACT: Boilers type T7T-230-2 intended for burning lean coal ivere installed at Minsk Heat and Electric Power Station No.3. At the station the boilers were adapted to burn anthracite dust, of the three boilers two were reconstructed to have liquid ash removal and to operate at constant high loads. The third boiler had dry ash removal and was used to follow load variations. The reconstruction of the boilers to burn anthracite dust, with liquid slag removal is then described. The general arrangement of the reconstructed boiler with horizontal slag hearth and two cooled slag holes is illustrated in Fig.l. Boiler No.l. was reconstructed in this way and operated -with liquid slag removal for three months. It was found that when combustion was steady the slag was not liquid enough and the slag holes clinkered up every three or four days, so that the boiler had to be stopped for deslagging. Because of this unsatisfactory experience, in adapting boiler No.3. use was made of the liquid ash removal arrangements illustrated in Fig.2, which was developed by the Taganrog Boiler Works and in which the hearth contains four ash holes, one Card 1/3 of which is especially large, and one slag pit filled with water. 96-3-7/20 Rationalisation of the combustion of anthracite dust at the Minsk Heat and Blectric Power Station No.3. The centre turbulent burners were also lowered 2 metres. 117ith this hearth there was no accumulation of liquid slag on the hearth. The performance of Boiler No.3. was satisfactory. With a milling fineness of 7% on an 88 micron sieve the heat loss due to mechaziical non-combustion is 5.2% and lose with the flue gases 6.0~. The efficiency of the boiler is 87.7%. The ash hole cooling coil was unsatisfactory and a new one was constructed as illustrated in Fig.3. When burning anthracite dust there is a strong tendency for slag to stick to the heating surfaces, particularly if combustion is good. Intense slagging of the heating surfaces was observed on boiler No.3. and this gave rise to very uneven temperature distribution in the superheater as will be seen from the graphs in Fig.G. Because of ash deposits it was necessary to shut down the boiler to prevent damage to the tubes. Attempts to remove the deposits by hand were unsuccessful, but the problem has now been partially solved by short periods of washing with water at a prosaurc of 10 atms idiilst the boiler is operating. This does not endanger the superheater tubes. Tube slagging was not observed on boilers operating with dry ash removal. There was also inteusive ash deposition an Vile tail heating surfaces in the gas temperature range 450 - 6500C. Card 2/3 The output of the boiler was indeed limited because of the increased 96-3-7/2G Rationalisation of the combustion of anthracite dust at the Minsk Reat and Electric Power Station No.3. resistance of the gas ducts. Further improvements were made on Boiler No.4. which commenced operation in June, 1957. The method of delivering fuel to the furnace was improved, the embrasures were reconstructed and conical ends wore used on the burners instead of cylindrical. Until now air has been used to transport dust to the furnace, a large part of the heat of the air was used to dry the fuel. After reconstruction, the air temperature will be increased to 350 - 4000C. The dusty air from the fuel preparation system is passed into the furnace through special nozzles arranged an shown in Fig.G. The new conical embrasures are illustrated in Fig.7- The performance of boiler No.4. after reconstruction is characterised by the following data. When the fineness of milling is such that there is 10.5% residue on an 88 micron sieve the heat lose due to mechanical non- combustion is 4.4g, the heat lost with the flue gas is 6.5% and the boiler efficiency is 88.5%. The use of liquid ash removal with the burnerw installed lower down reduces the lose due to mechanical non- combustion and reduces the temperature of the outgoing flue gas by 20 - 300C.

However, the possibility of narrow-ing down the field of experimontation thanks to a knowledge of the physical properties of a piece of apparatus has evidently not been studied at all. The present article is devoted to a mathematical consideration of this question. The article considers a piece of apparatus Whose state at any given moment of time is described by a quantity xwhich is called the load, Thus, every possible manner of using the apparatus over a period of time can be described by a function x(t), o.:!~ t e,-oo, which is called the trajectory of the load* The total class of permissible trajectories is designated as M. The general problem Card L 09505-67 XCd 14R, AT6025454 6 1 -onsists in seeking an operator (P , determined with M, such that 9 (x) = p(t) is the lifferential function of the distribution of the timo of continuous operation of the ipparatus, described by the trajectory x, After an extended mathematical exposition %*.author arrives at the expression xdt exp dt. fere'r As any given moment of time.

SOV/74-28-6-3/5 TITLE: Modern Views on the Adhesion of High Polymers (Sovremennyye vzglyady na adgeziyu i7sokopolimerov) PERIODICAL; Uspekhi khimii, 1959, Vol 26, Ur 6, pp 701 - 740 (USSR) .ABSTRACT: It is the object of the present paper to give a survey, as com- plete as possible, of the papers on the adhesion of high poly- mers. Principal attention is paid to the adhesion of high poly- mers to high polymers, as this problem is most important from the standpoint of national economy. Table I indicates various on of their purpose. The data adhesives with a short descripti ' are taken from reference 1. The tirm "adhesion" usually refers to the adherence of 2 different contacting substances. Adhesion is divided into 2 types: 1) the specific or real adhesion re- presenting a force of attraction between the adhesive and the adhesive surface, and 2) the mechanical adhesion where the ad- heaive enters the pores of the adhesive material and is kept there mechanically in a hardened state. Tile first type occurs in case of perfectly smooth and compact surfaces and is caused by the specific interaction between adhesive and substrate mo- Card 116 lecules. The second type is characteriatic for porous or crack- Modern Views on the Adhesion of High Polymers SCV/"4-2F,-e1-3,!1r ed surfaces and is caused by mechanical factors. T-hc. r-art play- ed by the nechanical factors in stickinE porous materials waa discussed in detail in the papers (Refs 20-22). The d.:)t~rrina- tion of adhesive power con3ist3 of.kwu proceasos: 1) lishine a contact between adhesive-,A'a substrate surface; 2) separating these surfaces, and determininE the force required for the separation (Ref 23). Dependin- on the kind of destruc- tion of the connection, 3 tYPes of separation are distir6ulsh- ed: 1) adhesion separation when a complete separation into layers takes place between adhesive and substrate, 2) cohesion separation when the crack either runs through the adhesive or through the substrate, and 3) mixed separation when the sepa- ration of the two materials occurs partly in the place of the original contact, partly through the adhesive or substrate. The quantitative determination of adhesion can only be carried out on the basis of adhesion separation as otherwise the cohe- siveness of one of the components would be determined. The quantitative determination of adhesion of polymers can be car- ried out - just as in case of "autohesion" (autogeziya) - by means of separation, or separation into layers. The methods of Card 2/6 determining the adhesive power were .described in references 1, Modern Viewe on the Adhe9ion of HiCh Folyme-ra SOV/74-28-6-3/5 8,14,23-39. For the case of a contact betwoon two liquidia, tho theory of adhesion has been nearly perfectly developed. For the case of a contact between solids and liquids, different authors suggested different methods of determination (Refs 40-43)- In determining adhesion between two solids, the nonequilibrium. ad- hesion function is determined by ordinary methods of separation, and separation into layers. It has been attempted recently ('Ref 44) to determine the equilibrium adhesio n function between so- lids indirectly. Former papers on adhesion (Refs 45-50) have a purely empiric character, and are o-f little importance to the theoretical understanding of*specific adhesion of hiE;h poly- mers. The adsorption theory of adhesion has been widely spread abroad. This theory explains adhesion by Van der 'Waals inter- action between molecules of adhesive and substrate (111efs 52-61)- This theory was further developed in the papers (Refs 8,26,3 " , 57-74). To explain the facts which do not fit into th,a frame of the adsorption theory, DeryaGin and Krotova (Refs 8,73,74) sug- gested the electric adhesion theory. Mmny circumstances point to the presence of electrical phenomena at the separation of sticked surfaces (Refs 25,33,73-82). Although the electric ad- Card 3/6 hesion theory is superior in some points to the adsorption Modern Views on the Adhesion of High Polymers SOY/74-2-0-6-3/5 theory, it can be applied to the case of adhesion of hieh poly- mers with r9striction only (Refs 8,83-88). In recent years, the diffusion theory has been suGgested (Refs 18,83,88). It is based on the essential peculiarities of high polymers, cq chain structure and elasticity of macromolecules, whereby the .latter can change their configuration due to thermal motion. Other papers concerned with this theory are references 18,2'1, 78,83-101. The investiZation of the effect exerted by tha cej.,,- ditions of formation of the jointinf; seam on the adhe3ion of high polymers, the testina of the jointing seam, the dimensicns, shape and polarity of the macromolecules, as well a3 a number of technological factors, confiri; the correctness of the dif- fUS4on theory. In considerinG the effect exerted an adhesion by tho conditions for the formation of the jointing seam, the fol- lowing factors are taken into consideration: the contact time between adhesive and substrate (Refs 83,102), the pressure (Refs 31,84,102), the temperature of adherence or of the ther- mal treatment of the sticking seam (Refs 59,61,83), the con- tent of solvent in the adhesive (Ref 103), the thickness of ad- Card 4/6 hesive layer (Refs 8,21,31,51,104-113), the surface relief of Modern Views on the Adhesion of HiGh Polymers SOV/74-26-6-3/5 the adhesive (Ref 8). In investigating the effect exerted on adhesion by the testing conditions,,the following factors are considered: the effect of the separation rate (Refs 8,23,26, 114), of the temperature (Refs 6,147), of the exposure to the action of X- and gamma rays (nef 8), of the Geometric dimen- sions of the sticking surface (Refs 115,31)- In investigating the effect exerted on adhesion by the character of the adhe- sive and of the substrate (Refs 54,59,116), the molecular weight (Refs 57,59,116), the form of molecules (Refs 16,57,59, 1 1), and the polarity of molecules (Refs 57,59,116) are con- sidered. Besides, some technological factors play a decisive part.; application of one solvent common to the adhesive and the substrate (Ref 118)., introduction of plasticizers into the adhesive (Refs 8,58 9,84,114), introduction of fillers in- to the adhesive (Ref 84~, comparison of adhesion and co-vul- canization (Refs 1,9,102,120,121), the storage of rubber mix- tures before doubling.(Refs 28,84,102).

For this purpose, commercial butadiene acrylonitrile co- polymers (rubbers) of the types CIK14-18 (SKN-.18)p rKH-26 (SKN-.26), and C K14-40 (SKN-40) were isolated from benzene solutions by means of methanol fractions.

Effect of the S/190/60/002/005/002/015 Molecular Weight of Butadiene Acrylonitrile B004/B067 Copolymers of Different Polarity on Adhesion to Polar and Apolar Substrate temperature according to the method described in Ref. 8~ Some samples were heated to 50 - 2000C for 30 min under load and, aft6K they had cool- ed the layers were separated by means of a dynamometer of the TsNIKZ (Central Scientific Research Institute of the Leather-footwear Industry). The experimental data are given in Figs. 1-5 and Table 2. The results in- terpreted in terms of the diffusion theory are given. With increasing molecular weight the adhesion of each of the copolymers decreased to a certain limit of the molecular weight (300,000 - 350,000). With still higher molecular weight it remained approximately constant. With in- creasing temperature, adhesion of the fractions increased and attained almost the cohesion stability of the polymer fraction. The temperature at which this stability was attained was lower with lower molecular weight, If the glued sample was not heated, adhesion of the copolymers to the polyamide depended only little on the polarity of the copolymer. Heated gluedisamples were dependent on polarity. With decreasing content of polar groups adhesion increased. The weaker adhesion of the more strongly polar copolymers to the strongly polar polyamide is exDlained by a pure- 4 ~inqjic effect, i..e., by the low flexibility of the macromclecules 8382.2 Adhesion of Polymers.

Effect of the Molecular S/190/60/002/005/002/015 Weight of Butadiene Acrylonitrile Copolymers B004/Bo67 of Different Polarity on Adhesion to Polar and Apolar Substrate of such polymers and the intensive cross--linking that suppresses diffu-- sion. The adhesion of commercial butadiene acrylonitrile copolymers which are not separated into fractions, to polyamide in non-heated glued samples did not depend on the content of polar groups but on the content of frac- tions of different molecular weight. At higher temperatures, adheaicrL depended on polarity. The adhesion of the copolymers to the apolar sub - strate (polyisobutylene) is low and depends neither on polarity and molecular weight nor on temperature.

Adhesion was expressed by the resistance P to layer separation of the films in 9/cm. A dynamometer of type TsNIKZ (Teentralinyy nauchno-issledovatellskiy institut zamenitele kozhi (Central Scientific Research Institute of Leather Substitutg (Refs 2, 3~ was used to separate the layers at room temperature and at a separation Velocity Of 0.3 cm/sec. A table (p 188) lists the results obtainede These data may be divided into 3 groups concerning: 1) a purely cohesive layer separation (these data characterize the cohesive strength of caoutchouc, K); 2) a purely adhesive layer separation (these data characterize the binding strength - adhesion, A); 3) a mixed type of layer separation (S). Type K comprises nearly all luted samples with sodium-butadiene/caoutchouc and most samples with SKBM-50 butadiene Card 1/4 Adhesion of Synthetic Rubbers to Different High- S/153/60/003/01/051/058 molecular Substrata B010005 caoutchouo. The high adhesion of SKB-50-sodium-butadiene caoutchouc is probably due to the relatively low molecular weight and the aoarce and sufftiently long branchinge of its macromolecules. The lower adhesion of sodium-butadiene caout- chouc to polyethylene is due to the crystallinity and high density of the molecular packing of polyethylene. Therefore, the macromolecules of the adhesive cannot diffuBe into the depth of the substratum. The data of the table contra- dict the current opinion that the adhesive propertiee of sodium-butadiene caoutchouc are bad. As is known, the molecules of SKBM-50-butadiene caoutchouc are little branched. Therefore, its adhesion is weaker than that of SKB-50, For all pairs of substances luted together with the same adhesive, which show a de- struction of type K, the resistance to layer separation is nearly equal and in- dependent ofthe nature of the substratum (exception: SKB-50 with cellophane). Among the luted samples, which are destroyed according to type A, isoprene caout- chouc shows a higher adhesion to all substrata than natural caoutchouc. The weak adhesion of natural oaoutchouc is the more astonishing as it possesses ex- cellent adhesion to itself. Butadiene-styrene caoutchouc with low styrene content (SKS-30) shows a much lower adhesion than pure butadiene caoutchouc. In the copolymer SKS-30, the molecular chains become much stiffer under the influence Card 2/4 Adhesion of Synthetic Rubbers to Different Hi(;h- 3/153/60/003/01/051/058 molecular Substrata BO11/BOO5 of pb:nyl side groups# and diffusion is Inhibited, A higher styrene content (abov '30%) reduces adhesion even more* An increase in methyl-styrene groups in butadione-methyl-styrene caoutohoucs weakens their adhesion.

E040/E485 of polymers to polar and non-polar substrata. Furthermore, the results obtained were compared with data obtained for polydisperse products. The investigation was made on specimens of butadiene- acrylonitrile copolymers with various concentrations of the olar component in the macro-molecule (nitrile rubbers CV.H-18 KNI-18), C.XH-26 (SKN-26) and CKH-40 (SKN-40)). Molecular N weight was determined by the light dispersion method, while the acrylonitrile content, which varied from about 19 to 40%, was calculated from the nitrogen content. A polyamide substratum was used in the tests designed to elucidate the effect of molecular weight on adhesion and a polybutylene substratum was used In examining the effect of polarity. Adhesion between the various polymer fractions and the substrata was determined at a constant rate of separation (0-3 cm/sec) using an apparatus designed at the TsNIKZ (Ref.9: S.S.Voyutskiy, V.M.Zamazly, Kolloidn. zh., 1953, v-15, 407 and Ref.llg A.I.Shapovalova, S.S.Voyutsk-iy., A.P.Pisarenko.

It was found that the adhesion of butadiene-acrylonitrile copolymers to polyamide substrata diminishes with rising molecular weight of the copolymer and then remains constant for molecular weights exceeding 300 to 350 thousand, The adhesion of all specimens was found to be considerably improved with rising curing temperature. This applies especially to the lower molecular weight fractions (transition from adhesive to cohesive bond type). Curves were plotted for the variation of adhesion of butadiene-acrylonitrile copolymers to polyamide substratum as a function of the concentration of the polar groups (acrylonitrile). It was found that, at room temperature, the strength of adhesion depends little on the polar groups. However, if the temperature of the contact is raised to 1500C. adhesion drops sharply with increasing polarity and, conversely, the strength of adhesion rises rapidly with curing temperature as the polarity of the specimens is decreased. A theoretical explanation is given of this dependence. Adhesion data from tests Card 3/5 31897 S/643/61/000/000/002/007 Effect of molecular weight ... E040/E48.5 on polyamide base of various fractions of butadiene-acrylonitrile copolymers were compared with those obtained in parallel tests of the adhesion of non-fractionated products (polydisperse). It was found that, in the first case, adhesion of contacts at room temperature is practically independent of polarity but that in the second case of polydisperse fractions, the strength of adhesion diminishes with increasing content of the polar acrylonitiiie group. At elevated temperatures, the effect of polarity on adhesion is identical for non-fractionated products and the fra,,~.tions with molecular weight of about 320000. An examination oi the influence of the nature of substrata on the adhesion of polymers of different molecular weights and polax-ities showed that the adhesion of polar adhesives to non-polar substrata is rather low and is independ-~-nt of the molecular weight and polarity of the adhesive and the temperature of the contact.

Adhesion to polyamide of graft ana modified polymers obtained from carboxylic butadiene styrene rubbers and 6.-caprolactam and its derivatives PERIODICAM Vysokomolekulyarnyye soyedineniya, v. 3, no. 5, 1961, 775-782 TEXTs B. A. Dogadkin et al. (Kolloidn. Zh. 20, 43, 1958) proposed an in- termediate polymer as binding agent in order~_Tto increase the binding strength between natural and butadiene styrene. The diffusion of the chains of the natural rubber of the graft polymer into the natural rubber and the diffusion of the butadiene styrene rubber chains into the butadiene styrene rubber would give a firm bond. Correspondingly, the graft polymers produoed by V. A. Kargin, Kh. U. Ustanov, and B. I, Aykhodzhayev from styrene and viscose showed a strong adhesion to rubber. Thus, graft and modified polymers on the basis of carboxylic butadiene styrene rubbers (CBSR) and &-caprolactam and its derivativee would be able to increase the Card 1/10 22569 S/190/61/003/005/012/014 Adhesion of polymers...

The authors studied the ad- hesive properties of the above graft and modified polymers whose synthesis has been described previously by the second author (Ref. 3: Mezhdunarodnyy Simpozium po makromolekulyarnoy khimii (international Symposion of Macro- molecular Chemistry), Moscow, June 1960, sektalya III, p. 224). Their structure has been ascertained by means of infra-red spectrum and chemical determination of nitrogen and carboxyl. The films of the polymers and the polyamlde were glued together and then submitted to a heat treatment of up to 100 C and tested for exfoliation by means of the dynamometer of TsNIKZ.

(The introauction of groups of higher polarity (CON-H) than the COOH group causes an.increased rigidity and reduced diffusibility by starting intra- and intermolecular reactions. In case the chains are shor.t (3 caprolactam members)"for the safe quantity of polyamide, the' number of individual ends-diffusing into the polyamide increases. Tem- perature rise incteases the Brownian movement and, thus, the adhesion. The strongly polar CONH groups of the gr4ft polymer have twice as much cohesive energy as the COOH gtoups of the CBS9; they cause a particularly .close chain packing and enable the.forming 9f.hydrogen bonds. S-12 gave good binding results, since it contains a definite amount of bound monomers. Modified CBSR polyiaers containing still some methyl ester of the ~.-amino caproic acid were studied. Also in this case, the cohesive power of these polymers surpasses that of the initial polymers, but their adhesion is independent of the amount of ester. The introduction of poly- amide chains into CBSR containing-more than 3* of styrene reduces the-ad- hesion due to increasing rigidity. Increase of the contact temperature increases the adhesion and maintains the adhesive character of exfolia- tion. As compared to the initial polymers, the cohesion is also higher.

Thus, adhesion is fundamentally dependent on polymers oX similar polarity in highly elastic or viscous state, i.e. with sufficient molecular mobility. Polymers modified by the methyl ester of ,-amino caproic acid,(!' '-24 and "-25) (3-24 and S-25) are more adhesive than polymers with polyamide chains (.-17 and '"-19) (S-17 and S-19). In the absence of styrene, a slight addition of caprolactam does not deteri- orate.the adhesive properties of rubber. The binding force between the rubber (SKS-ZOA) and ordinary material (0- 5 kg/cm) increased for material impregnated with graft polymbr from CBSR and polyamide to 0-95 kg/cm. For -'~-(SKB) rubber and caprone tissue impregnated with butadiene poiymer modified by ~-caprolactam monomer (polymer _-33 (S-33~)' the binding force amounted to 0.8 kg/cm (0-4 kg/cm without impregnation).
