The present paper des- cribes investigations of copolymers on the basis of amino-en- anthic acid and capro-lactam in different properties of weight; the experimental investigations were made in co-operation with L.H. Vlasova. The investicatione were made in open ampoules, in nitrogen atmosphere at 2600 an& in 6 hours. The specific weight of the copolymers thus obtained varied from 0.75 to 0.78.

Polycondensation of Aliphatic w-Amino Acids and Diamine Salts of Dicarboxylie Acide in the Solid Phase PERIODICAL: Khimicheskiyevolokna, 1959, Mr 5, PP 13-18 (USSR) ABSTRACT: The authors investigated the general rules of polycondensation in the solid phase by maana of three Lo-amino acids (amino- enanthic acid.11 aminopelargonic acid, aminoundecanic acid) and the hexamethylene-diamine salts of the adipic, terephthalic, and thiodivalerianic acids. The temperature dependence of the reaction was observed by continuous weighing during the condensation process) and by measuring the quantity of water separated out. It was shown that the reaction takes place within rather small 0 temperature ranges (6 - 15 C) near the melting point of the ini- tial and end products, the temperature coefficient of the reac- tion rate being rather high. If the three amino acids are com- pared with respect to the reaction rate of polycondensation at the same temperature, the aminoundecanic acid reacts most rapid- Card 1/2 1y followed by the aminoenanthic acid, the aminopelargonic acid 66961 SOV/183-59-5-3/28 Polycondensation Reactions in the Solid Phase.

Polycondensa- tion of Aliphatic G)-Amino Acids and Diamine Salts of Dicarboxylic Acids in the Solid Phase being the BlOWeBt, With respect to the activation energy, the acids show the same order beginning with the aminioundecanic acid as the consumer of the least energy. As to the polycondensation of the hexamethylene-diamine oalto of dicarboxylic acids, it was shown that the higher the melting point of the salt is, the higher will also be the temperature at which the reaction starts'i and the wider the temperature range is within which the reac- tion takes place, the lower will be the temperature coefficient of the reaction rate. If the reaction takes place in the solid phase in open vessels at higher temperatures, hexamethylena di- amine will be separated out and, thus, excluded from the reac- tion. In this way, the reaction equilibrium is shifted to the effect that a formation of higher-molecular polyamides is not possible. The same applies to the reaction in the liquid phase (melt).

In the present paper the following acids were synthesized: n-amino-methyl-phenyl-acetic-(I), n-amino-methyl-phenyl- propionic-(II), n-amino-methyl-pheiiyl-butyric-(III) I and n- amino-methyl-phenyl-valeric acid (IV) ENH 2CH2C6H4 (CH2),COOH(n. -1-4) 1 - The corresponding n-chloromethyl-phenyl-alkane- carboxylic acids (Ref 3) servea as initial products. Since it is not possible to aminate the..,chloromethyl E;roup of these compounds immediately with a\ donia, this amination was carried Card 1/3 out by the decomposition of the complexes of Urotropin with Synthesis and Polycondensation of the n-Amino- SOV/79-29-3-50/61 Methyl-Phenyl-Alkane-Carboxylic Acids the n-halogen-methyl-phenyl-alkane-carboxylic acids. The synthesis of the Urotropin complexes was not carried out according to reference 4 (i-e- it proceeded from the above mentioned acids in which iodine substituted Cl), but the above mentioned substituted compounds were used directly and quantitative yields and cleavage products without iodine admixtures were obtained. The chlorine hydrates of the amino acids obtained by the cleavage of the Urotropin complexes were converted into free amino acids by the evaporation of their ammonia solution. The dry residue consisted in a mixture of ammonium chloride and free amino acid which was liberated from its mineral ingredient by the recrystallization from water. The synthesized amino acids have no distinctly marked melting point and are not easily soluble in water. In the case of heating they are transformed into high-molecular polyamides. These polyamides ~Lre produced not only in the case of a melted state of the initial products, but already at temperatures below their melting point, i.e. in dry state which is very important for the production of the thermolabile polymers.

By the investigation under reviews the authors succeeded in producing amides hitherto not described in publications. Polyamides (with a siloxane group) obtained on the basis of dicarboxylic acids of the aliphatic series are known to exhibit caoutchouc-like pro- perties in a number of cases (Ref 3). The condensation of aromatic dicarboxylic acids (witYL a siloxane group) with hexamethylane dia~aine yields fiber-forming polyamides"(Ref 1).

The authors intended to investigate the properties of polyamides produced by using the silicon- containing diamines.prepared by thei~iselves. As was to be expected from data contained in publications, the fiber-. forming polyamides can be produced sololy by condensation of the said diamines with arontatio aoide. The authors therefore used diamine salts and terephthalic acid for their experi- ments. The silicon-containing -dinitriles: ENC (Cli 2)3 -Si(CH3) 23 2O'[HC(CH 2)3_3 i(CII 3)(C2H5~ 20 and CNC(CH 2)3'_S'(C2"9)212O were obtained by hydrolysis of the cyano-propyl-dialkyl-chlorosilanes (Ref 4). 9 .CH 2' CH~ atsi~('CH 3)2 CH3was obtained from a mixture of NC.CH 2' CH 2' CH2Si(CH 3)Cl (120 g) and anhydrous pyridine (104 9) in anhydrous ether (800 ml) on cooling with ice water and on adding 40 g of absolute methanol during 1 h of vigorous stirring. This substance has not yet been described in publications. The nitri3es were hydrogenated in 6 73 18 Catal7tic Hydrogenation of Silicon-containing SOV/20-129-5-28/64 nitriles and the Fiber-forming Properties of rolyamidee Obtained From t e Amines Produced Thereby a rotating steel autoclave with nickel skeleton catalyst and ammonia. The amine fraction was readily distilled by fraotionating the catalyzate. Its degree of purity was 97-109~ (Table 1). Table 1 also specifies the experimental conditions and yields. Table 2 supplies the constants of amines and their derivatives. In this manner the following symmetrical di46-amino-butyl)-tetra-alkyl disiloxanea were pro.duceds I) (see Scheme) along with its salt with terephtha- lie acid (C 12H32 Si 2N2O.CaH602); 1,) (see Scheme) together with its salt with terephthalic acid (C 14 U36 Si2N20C8H6 02); III) see Scheme) together with its salt with terephthalio acid ~C 16H40 Si2 N2 OCaH602) . The yield drops with the pro- longation of the lateral alkyl groups and is in 1 -927'0't , III II - 8Tj'1' ~ - 70%. Table 2 shows the constants of the amines and their salts with terephthalic acid. The yield of the salts was 80-85%. All amines obtained are colorless clear liquids, non-ooluble in water (they. form an emulsion), Gard 3/5 soluble in 5015 alcohol. The polyamides were obtained by 67918 talytic Hydrogenation of Silicon-containing 30V/20-129,~5-28/64 nitriles and the Fiber-forming Properties of Polyamides Obtained From r ~e Amines Produced Thereby heating (polycondensation) of the produced salts in nitro- gen atmosphere. They are pale-yellow, horny, elastic, trans- parent resins of amorphous structure, well soluble in cresol and concentrated H2SO4. They swell in hydrochloric and formic acid, but do not solve. Table 3 shows the condi- tions of polycondensation. All these polyamides, when melted9 yield fibers, which are dilatable by 300-400% at low temper- ature. The stability of the fibers is not very high. The re- sults obtained confirmed that the substitution of methyl radicals on the silicon atom by ethyl radicals causes the polyamide melting temperature to drop. The siloxane group in the principal chain increases the flexibility and elasticity (like the oxygen atoms). There are 2 tables and 6 references, 2 of which are Soviet.

Thi-lecturer gives a survey of abort- comings aacertained in the synthetic fiber,~~industry. The causes are: deficient equipment, nonobservance of produotion-re-jUlations,.and, bad raw materials.

Most technical improvements can be carried out by the fac---- -,riea wi-.,~.~aut cooperation of the GIPROIV (State Institute for the Design aud -f Synthetic Fiber Industry Establishments). The Kalinin Kombinat and Card 1/3 Repo~rt s/i83/60/000/02/08/025 B004/BO05 the Leningradakiy zavod (Leningrad Works) were able to increase the fiber break- in length to 19-20 km. Yor a further increase, modern equipment is necessary whfoh should be procured by the Rostovskiy sovnarkhoz (Rostov sovnarkhoz) and the Leningradskiy sovnerkhoz (Leningrad sovnarkhoz). The VNIIV (All-union Scientific Research Institute'of Synthetic Fibers) developed a viscose staple fiber with a breaking length,of 23-25 kmj its processing at the fabrika, "Oktyabriskaya Revolyataiya" (~~October Revolution" Factory) yielded satisfactory results. An ad- dition of modifiers gave positive results which were also confirmed by the TsNIKhBI (Central Scientific Research Institute of the Cotton Industry). The Klinskays. laboratoriya (Klin Laboratory) of the VNIIV ascertained that capro- lactam, polymerization is stopped much too early in the Klinskiy kombinat (Kiin Kombinat). Ventilation systems causing disturbing air eddies in the fiber forma- tion zone were planned there and in the Kiyevskiy kombinat (Kiyev Kombinat). 1 table shows that the quality of caprolactam is worse than in Eastern Germany an3 Italy. Standards should be improved. In recent years, ',,he VNIIV has left the worlt-l- ing out of many problems to the TsNIL (Central Scientific Research Laboratories) of the factories but qualified specialists were missing there. In 1960, the VNII7 will establish an automatized experimental plant.

Dyos,and reliable dosing apparatus are missing. The NIOPix (Scientific Research Institute of Organic Semifinished Materials and Dyes) shoul,~ relieve this situation. Almost no textile adjuvants and modifiers are being pro- duced in the Soviet Union. This is also a problem to be solved by the institutes of the Gosudaretvennyy Komitet Soveta Minletrov SSSR po khimii (state Committee on Chemistry of the Council of Ministers USSR). The lecturer reports on some ex- periments of VNIIV in this respect. Above all, there are no experimental plants to check the experimental results. There is I table.

Fibers with additions of water-soluble copper salts and three- component additions were tested for heat resistance. They were heated for 61 24, 48, 72p and 100 hours'to 1500C, and for 2, 8, 14, 24, and 36 hours to 1800C. It was shown that a simultaneous introduction of multi-component additions during fiber polymerization yielded maximum heat resistance. 0-03% copper acetate, 0.25% sodium phosphate, and 2% p'otassium iodide were, used. This inhibited the decomposition of the fiber during heating. Resistance to tearing increased by q. on '14 hours' heating to 1800C.

TITLE: Study of the Conditions of Copolymer Production From Acrylo- nitrile With Alpha Vinyl Pyridine, Suitable for Fibration PERIODICAL: Khimicheskiye volokna, 1960, No. 6, pp. 15-19 TEXT: The paper reports on the results of studies concerning: a) copoly- merization of acrylonitrile (AN) with a-vinyl pyridine (a-VP) for the purpose of producing a copolymer with predetermined molecular weight and the determination of the optimum concentration of the spinning solution, b~ the d6termination of the optimum concentration of the salt solution, a the conditions for the production of suitable spinning solutions, and d) the trial formation in precipitating baths with aqueous salt solutions and the study of the physical and mechanical properties of the fiber ob- tained. In copolymerization, the molecular weight of the copolymer is influenced by the amount of the initiator (azo-di.-L'sobutyric acid-dinitrile), the temperature, type of solvent and amount of the regulator (monoethanol amine).

The influence of the amount of regulator on the change in time of the intrinsic viscosity (Fig. 1), and the dependence of the intrin- sio viscosity on the regulator concentration (Fig. 2) are determined. The change of the intrinsic viscosity of the solution in dependence on the amount of initiator used is mentioned in Figs.3 and 4. It can be seen from Fig- 5 that with rising temperature, the intrinsic viscosity of the co- polymer produced drops from 2.5 at 600 C to 1.3 at 75 OC. The deDendence of the intrinsic viscosity of the copolymer on the initial con;entration of the monomer mixture (Fig. 6) shows that the probability of a chain rupture through the solvent increases with sinking concentration of the monomers in the solution. As may be seen from the tabulated data con- cerning the conditions of the copolymerization of AN with a.-VP in the production of spinning solutions, the rate of polymerization in 45 to 50% sodium thiocyanate, under otherwise equal conditions, is always tha same and the copolymers have the same intrinsic viscosity (1.39 to 1.4). Fig- 7 shows the dependenceof the Viscosity Of a concentrated sodium thic. cyanate solution on the intrinsic viscosity of the copolymer.

Polycondensation is rendered difficult because of the instability of the carboxyl groups, and because of chain cleavage owing to cyclization of the end group as a result of a favorable mutual position of the amino groups and CO groups of the amide bonds. The high- molecular PA of 4.-AMCA--ahd trans-4-ACBA cannot be spun from the melt owing to decomposition. The PA of cis-4-ACBA was not pure, bubbly, colored and low-viscous.

The p-phenylene diacetodi- nitrile (m.p. 950-970C) was prepared from acetone cyanohydride and p-xylylene dibromide. Hydrogenation was carried out at 1000-1050C and an initial hydrogen pressure of 100 atm in a rotating autoclave of 0.175 lit capacity. Dioxane, methyl alcohol, or ethyl alcohol containing some er ammonia were used as mediums.

The catalysts were then washed with water up to neutral reaction against phenolphthalein. Cobalt skeleton catalyst leached with 25-3W6 aqueous alkali solution at maximally 150C (Ref. 5: see below) was used in some experiments. Diamine'yields are strongly influenced by the nature of the catalyst and its preparation method, The yield is 64-65% in the case of nickel skeleton Catalyst, 74% with cobalt skeleton catalyst leached at 900-100OC9 and 94% with catalyst prepared by "cold les,ching". The authors also studied the polycondensation of p-(P,pl-diamino-diethyl) benzene with adipic acid and terephthalic acid. Addition of acetone to an equimolar mixture of aqueous diamine- and adipic acid solutions precipitates the salt. This salt is crystallized twice from water, yielding a white crystalline substance, m.p. 2000-2020C (C 16H26N204). The polyamide was obtained by polycondenaation of this salt at, 2600-2800C. Polycondenoation occurs in the solid phase below the melting point of the polyamide. This polyamide based on p-(PIPI-diamino- diethyl) benzene and adipic acid was also prepared at 200C by heterophase polycondeneation: reaction between the aqueous diamine solution (with sodium carbonate added) and adipic chloride in benzene.

It is soluble in concentrated H2SO4? cresol, formic acid, hydrochloric acid, and insoluble in organic solveat6. Polyamides of higher_mol wt. are-obtained by increasing the reaction temperature and reactiontime. The relative viscosity of these polyamides in concentrated H2804 is increased1rom 1.73 to 2.69. By spinning these high-molecular polyamides from their melts at 3350-3400C fibers capable of orientation at high temperatures were obtained. The polymer properties are also affected by the purity of the amino Bait used. If the salt is only recrystallized once, colored polyamides of lower molecular,weight are formed.
