"lectrochem., 63, 943, 1959), the behavior-of p- and n-type Ge (resistivity 1.0 ohm-cm, diffusion length 0.5 CM) in 0.1 N H 2S0, was studied in the presence of 0-15 - 0.03 M X2 Cr207at ro-om temperature. Results: (1) With p-type Ge~ the potential of anodic dissolution increased in the presence of the bichromate by,0.2 v for the uhole range investigated (0 - 1.6 ma/cm2). (2) With n-type Go, the potential of anoxic dissolution increased whereas the saturation current. dropped to nea.-ly one-half. Exposure of the Ge electrode to light eliminated the bichromdte effect.

Since the ordinary single crystals of 6armanium are not strictly homogenious, specially grown crystals of n-germanium with')o z 3 obm-cm and length of the order of 0-7 mm, containing ~ minimum, amount of impurities and the density of disloca- tions-of 50 disloo./cm and also germanium ~rith tbe saipa electric pd physical arameters but having a density of dislocations -6o104 dialoc./cm2 were used for p this investigation., The anodic polarization curves were obtained by the potentio- Card L ....... lAcamiON NR-. AP4033398 Istatic method in 0.1 N 112SO)t (Fig. 1). The experimental reaulto chow that the :increase of the limiting current during the anodic dissolul',ion of garmanium is I ssociated with an additional generation of holes on come parts or the electrode la surface. A higher concentration of Cu and Ili on such parts of the electrode may lead to the formation of the high resistance micro regions where the acceptor impurities compensate for the main part of donor bmpuritien or it may lead to segregation of Cu and Ni into a separation phaseo primarily at the places of din- ruption of the crystal lattice. In the areas of germanium on which the coaductivi-~ ity is close to the bulk conductivity, the limiting current due to holes is much :greater than on bulk n-germanium. Upon increase of anodic polarization these izones may completely change the type of conductivity. The p-regions, which occur at the n-germanium electrolyte interface will carry a large fraction of current., thus individual areas of the electrode surface dissolve more rk pidly than others. ;A segregation of Cu and Ili in a separate phase in the germanium 'crystal may be !produced due to break-through and local generation. This iras varified by measuring ~the photoelectric potential as a function of the potential of gexuanium electrode ,,in 0.1 11 H2S04- "The authors express their gratitude to L. 1. Koleanik and Yu. A.

ABSTRACT.- This report presents for the first timo data obtained during the study of free radicals with the reaction center on a nitrogen atom. It was established that RNR type radicals are highly active in reactions leading to the separation of the H-atom from the carbon molecule, additional reactions to the vinyl double bond and are capable of exciting the polymerization process. Using dimethyl- diphenyltetrazene as an example, the authors established the monomolecular nature of tetrazene deoomposition during heating in a solution. The activation energy of this reaction was calcu- lated from kinetic data by the Arrhenius equation and fixed at Card 1/3 33 kcal/mol.

Part 9 on a nitrogen atom to excite the polymerization process was verified on a styrene-dimethyldipht.-rqltetrazene system (See Fig.2). The ability of alkylnitrous radicals to react with saturated and unsaturated hydrocarbons was determined by studying the products of thermal decomposition of tetramethyltetrazene in isopropyl- benzene and in alpha-methylstyrene. Tetramethyltetrazene appears to be of high thermal stability; at 1300 it deccmposes in the solution at a slow rate. The constant of the decomposition rate at_J450 1 isopropylbenzene at a 0.7 mol% concentration is 0.56# 10 SeA. The complete absence of dimethylamine in the products of tetramethyltetrazene decomposition in alpha-inethylstyrene indi- cates that the free dimethy1nitrous radicals do not become dis- proportionated.

The intensity of this inter- action was estimated indirectly by coiapa:ting the decrease of methane (produced accordinC to the reaction R.+LH--:~RH+L.), with the yield of CH when the process takes place in a sat- h urated hydrocarbon. e internal double bond is by far less capable for the addition of free radicals than a double bond of the vinyl type. The investigation of the interaction of free methyl radicals with polymers led to the same conclusion.

Transition to very viscous media leads to a decrease of the Ale of effective radical reactions. The wcond part of this paper deals with the interaction of the free dimethyleyanomethyl radical with 2- butene. The addition of this radical to an internal double bond is realized onlyto a very insignificant extent, Under the conditions of the experiments discussed in this paper these radicals have a tendency to recombine. Finally the experimental part is discussed. The authors describe the decomposition of methyl-phenyltriazene in several media and also the products of the decomposition of azoisobutirric acid in 2-butene, There are 2 tables and 4 references, 2 of which are Soviet.

TITLE: The Cell Effect and the Thermal Stability of Polymers (Effekt kletki i termostabillnost' polimerov) PERTODICALi Doklady Akademii nauk SSSRp 1956P Vol- 12or Ur 4, PP. 783-785 (USSR) ABSTRACT: A great number of organic substances are known whose thermal stability in much weaker in the solution or melt than in the solid state. The most typical examples are compounds with unstable bindings (pemxideB, azo- and diazo-compoon4n) which begin to decompose only at their melting temperatur-~ At the same time they decom;ose much quicker in solutions and at a much lower temperature (Table 1). According to the authors' opinion the following experimental results render it possible to relate the mentioned phenomenon to a rapid increase of the cell effect (- reaction of the primary re- combination of the free radicals) in viscous and solid media. As was proved already earlier the thermal decomposition of Card 1/4 methyl-phenyl triazene in a medium of hydrocarbons leads The Cell Effect anqthe Thermal Stability of Polymers 801T/2o-12o--4-20,;'67 to the formation of methane and methyl-aniline (Ref 5)., It is most probable that the latter forms as a result of recombination of the radicals which are roloasad at the inomcnt of decompoLlition in the "cell". The authors proved that in the case of decomponition of methyl-phenyl triazene in systems of hydrocarbon polymers the methane yield decreases with in.- creasing viscosity of the medium. At the same time it was proved that the yield of the product of primary recombination.~ namely of the methylaniline increases (Table 2). The above mentioned data give evidence as to a considerable influence of the viscosity of the medium on the efficiency of inter-, action in the cello The results obtained render possible the discussion of a possible influence of the state of aggrega- tion on the thermal stability of thoia -bstances that contain unstable bindings (Table 1) as well as of the polymers that have a hign fusing temperature. The difference in behavior of such compounds in solid state and in solution (or melt) may be explained by means of the partioulLrly important part played by the cell effect in solid state. Polyparaxylylene decomposes only after having been melted, (at 4250). In the Card 2/4 solution this is the case already at 302 . These polymers The Cell Effect and the Thermai Stability of Polymers are apparently "ov.-rherttedll; only tif tpr tho temperature of vitrification th~?y undergo a destructilve di- oomposition when the viscosity o' the system decreans cof, siderably. Hence wo may concludc that thc thermal zta~41,it~, of polymers with a high melting temperature displays ab- rupt jumps in connPctJon with the transition from colid state into an elastic one and from the elastic state into the solution. From the above mentioned it may be concluded that the task of increasing the thermal stability c'i carbon atom chain polymers in vitrified etate concists above all in increasing their melting temperature, A high thermAl stability of rubber-like polymers can apparently only be reached by the stability of the akeleton bindings of the main chain, There are 3 tables and 8 references, 2 of' which are S)oviett.

Interaotion of booayl=6 Ethyl Magnesium Bromide With Halides of Titanium and Cobalt chloride in the presence of the three above-mentioned accoptors in the temperature range -2000 - 400C was investigated (Table 3),, The data given in Tables I to 3 allow the assumption that the reaction of,ethyl magnesium bromide with titanium- and cobalt salts - at least at the temperatures applied in the experiments - does not proceed via radical stages. It was seen in the experiments that the total yields of ethane and ethyleneq and their proportion are not affected by the presence of the above acceptors. The authors mention a paper by N. V. Kondyrev and D. A. Fomina (Ref. 1), and one by Yu. V. Koryakin (Ref. 11)o There are 1 figure , 3 tables, and 12 referencest 4 of which are Soviet.

Polymerization of Isopren Under the Influance of Organomagnesium CompoundsN Vysokomolekulyarnyye soyedineniya, 1960, Vol. 2, 110. 4, pp. 541-545 TEXT: The authors report on the polymerization of isoprene in cumene carried out by means of ether-free butylmagneDium chloride, bromide, iodide, dibutylmagnesium, and mixtures of butylmagnes~um iodide and dibutylmagnesium, as well as of phenylmagnesium chloride and diphenyl- magnesium at 900C and a concentration of the monomeric isoprene of 60 mole%. Results are given in Table 1: yield, 4 - 50%; duration of the reaction, 20 40 hours; ratio between monomer and organomagnesium compound, 1 0.007 - 1 : 0.044; vitrification temperature, -3 to -100C; intrinsic viscosity, 0.75 - 0.95; degree of unsaturation, 77 - 83%; content of 3,4-bonds, 93 - 98% (deteroined by means of infrared Card 1/3 84511 Polymerization of Isoprene Under the S/190/60/002/004/012/020 Influence of Organow-6itesium Compounds BOO0056 spectroscopy by Ye. I. Pokrovskiy the authors' inatitute). The polyisoprene obtained in this way was perfectly soluble in benzene, probably because of intramolecular cyclization of the polymer chain. It mainly contained 3,4-bonds, so that the vitrification temperature is considerably increased in comparison to 1,4-PolYisoprene. The kind of the halogen and radical of the organomagnesium compound did not affect the structure of the polymer. Fig. 1 shows the infrared i)pectrum of a polyisoprene sample. By adding complexing reagents, such as diethyl ether or triethylamine, the polymerization is retarded with an increase in the concentration of the reagents (Pig. 2, Table 2). Besides, a decrease in 3,4-bonds to 83 - 88% occurs (Table 3). In the experimental part, the authors describe the synthesis of ether-free orgenomagnesium compounds in cumene at 130 - 1400C, as well as in paraffin hydrocarbons in sealed ampoules at 1350C. There are 2 figures, 3 tables, and 5 references: 1 Soviet, I US, I British, and 2 German.

Otdoleniye khimicheskikh nauk, 1960, No. 9, pp. 1672-1674 TEXT: The authors investigated in how far the methane- and methyl aniline yields depend on the molecular weight and concentration of the polymer in the eane of thermal splitting of methyl-phenyl triazene in the cumene - V polystyrene system. As in shown by a provioun papor of the authorn (Ref 2), in solutions with 60% polystyrene (molecular weight 5000 to 200,000), tho reaction leads to a reduction of the methane yield as compared to the data obtained from the use of a pure solvent. Tho methyl aniline yield remains, however, the same as that obtained in the absence of the polymer. Only in the solution of polystyrene with a molecular weight of 600,000, and a polymer concentration of 60~6, the methyl aniline yield increases, while the Card 1/3 Reactions of tYe Free Radicals in Solutions. S1062160100013U10141021 CoaLmunication 17. Effect of the Viscosity of B023/BO64 the Medium on the Primary Recombination of Free Radicals methane yield decreases considerably (Table I ). Conmoquently, tho change of yields in methane solutions, containing polystyreno with a molecular weight of up to 200,000, cannot be considered as a result of the increase in viscosity of the medium. This would have certainly led to a higher yield of the product of methyl aniline primary recombination. The reduc- tion of the yield is more likely to be due to the difference between the relative activity of polystyrene and that of cumone than to hydrogrorl donors. This is in agreement with published data, according to which the H atoms in polystyrene are less mobile than in cumene (Ref, 3). The authors proved that also in systems containing conaiderably lower poly- styrene concentrations, the methane yield is reduced. The amount of the yield depends, as is shown in table 2, on the concentration only. The molecular weight of the polymer has no effect upon the amount of the yield. In systems with a high viecosity, the importance of the primary recombination of free radicals increases. This becomes obvious by the fact that the methyl aniline yield increases, while the methane yield decreases at the same time. There are 2 tab':--- and 5 references: Card 2/3
