The derived nitric acid esters evidenced a greatly reduced solubtl1ty in acetone whenever aldehyde groups-were present. In the acetic acid eaters, irrespective of the amount of aldehyde 67/49T65 USSR/Cheml.stry Cellulose Compounds Aug 49 ,(Coutd) groups contained, the quantity of acetic acid bore relation to the number of acetyl groups in tri- acetylcellulose.

Modern viscose cord fibers have a breaking length of 50 km at 10% elongation; 'he tensile strenbgt-h In wet. s'ate decreases only by 20 to 25% (Kh"m. volckna, 1959, Nr 1, P 15). Molecular heterogeneity, particularly the content in fractions with DP < 150-200 '. is detrimental to the physical and mechanical properties (ibid., 1959, Nr 2). Molecular homogeneity inflL*nces positively the properties of the fibers, and also affects their struc- ture; the viscoaity of cellulose solutions with identical' average DP decreases with the Increasing uniformity cf Card 1/4 the molecular weighLs (Bum, prom, 1958, Nr 9, p 4).

During the-past few years, the USSR has succeeded in synthesizing isoprene 1-abber (SKI), which on the basis of its molecular structure and its resilience shows almost equal properties to that of natural rub1j6r' The discovery of SKI brought about considerable changes in the synthesizing methods of r-abber'. _. The new way of synthesis was carried out using alkali lithium metal as a catalyzer. Today, new more efficient types of rubber are being pro- duced by "grafted" polymerization methods; two different hybrids might result from this process; bloc polymers or grafted polymers. Another means to increase the durability properties of rubber . is to apply irradiation with particles Card 1/2 of high energy. Discoveries made by various scientists recently Rubber 25-58-3-5/41 led to a remarkable success: they obtained urethan rubber which is twice as wear-resistant as natural rubber. , Urethan caoutchouc is obtained by synthesis on the basis of chemical products of the coal-tar and oil-processing. Recently, scien- tists discovered that an addition of 0-5-1-5~ of carboxyl- containing substances, e.g. acrylic or methacrylic acide, to the raw material produces new properties in rubber) which help to improve its durability.

One of the main consumers of rubber goods is the automobile industry.which absorbs 65 to 70% of the total rubber output. A new application of rubber is rubber- pneumatic suspension to substitute steel spring suspension, An important field of utilisation of rubber is the aircraft industry and, for instance, the TU-104 contains 126 000 -rubber components of 200 different types. Communications have been published on the production of small aircraft with collapsible and inflatable wings and fuselages made of rubberized fabric.

A, TITLEi On the Problems of High-Elast o*Synthetic Rubbers as comparel to Butadiene-Styrene Rubbers $ PERIODICAL; Kauchuk i Rezina, 1959, No. 11, PP- 1-7- TEXT~ In the USSR particular emphasis is laid on an increase in the production of butadiene-styrene. and butadiene-methyl-styrene copolymer rubbers because of their wear-resistance, high elastictiy, durability, tensile strengthletc. It is the intention of the Soviet Synthetic Rubber Industry to produce butadiene-styrene rubber with higher physico-mechanical properties, of lesser cost and easier to process. It was found, for example. that the introduction of small additions of carboxyl-containing monomers, such as methacrylic acid, into the polymerizing mixture, imparts new prcper- ties to the ternary copolymers: elevated thermal aging resistance, resist- ance to the formation of cracks, elevated wear-resistance and an elevated stability of adhesion between the rubber and the textiles. The carboxyl- containing rubbers yield strong vulcanizates not requiring fillers, whish Card 1/ 3 S11 38/59/000/01 t /C-0 ; /C, A051/AO29 On the Problems of High-Elastic Synthetic Rubbers as Compared to Bu-aiisne- Styrene Rubbers is an important factor in the manufacture of white and colored rubbers (Ref. !, 2). The disadvantage of the carboxyl-containing rubbers is the tendency of the rubber mixtures to scorching during the processing. An- other monomer as third component in the ternary copolymers recommended 13 methylvinylpyridine, which can increase the wear-reeistance and the aging- resistance in the rubber. However, these copolymers have not as yet been fully investigated. It is stated that many articles are still being made of natural rubber. Therefore, stress is laid on producing a synthetic rubber with equal elastic properties to natural rubber and having a number of advantages over it. The stereospecific polymerization is used for this purposep with lithium and Ziegler-type c.~~tAjysts.j Special need fer improved types of butadiene-styrene rubbers is felt in the production of tires for trucks, buses and aircraft, which repreaents 80;/1j of the total number of tires manufactured in the USSR. TheC KW(sKI Jtype high-elastiC stereo- regular rubber is the only one of its kind tested and suitable for manu- facturing heavy-vehicle tires in the USSR. The import of natural rubber can be reduced by expanding the production of the new high-elastic rubbers, Card 2/3 S/138/59/000/011/001/011 A051/AO29 On the Problems of High-Elastic Synthetic Rubbers as Compared to Butadiene- Styrene Rubbers by erecting new SKI plants, and by developing the production of isoprene rubber, both on the basis of lithium and complex cocatalysts of the Ziegler and other types. Research into developing and producing new types of high- elastic rubbers of the cis-1,4-butadiene type is recommended, in addition to ethylene copolymers with propylene, etc. which would surpass natural rubber- in their technical properties. A table is iven (Table 1) of the comparative properties of the SKI, natural andC Ke-30A(SKS-30A) rubbers. It is seen that SKI rubber is the most promising of the synthetic rubbers.

TITLE: A creative discussion on the perfecting of chemical fibers used in the rubber industry 916 PERIODICAL: Kauchuk i rezina,,,no. 5, 1961, 54 - 55 TEXT: The discussion which took place on February 20 - 22, -1961, was orga- nized by the Central Board-of the'VKKO im. D. I.,Mendeleyev, Sections for Rubber and.dhemical Fibers, the scientific,research iDstitutes VNIIV and NIIShP and by the-local organizations of the VKhO im. D. I. Mendeleyev..at.NIIShP.....V..V. Krashak, corresponding member of the USSR.Academy.of.Sciences, spoke qn.the synthesis of new polymers. Some of the most promising new methods of polymer synthesis were given as follows: 1) stereospecific polymerization, 2) grafting and block-copoly- merization, 3) cyclopolymerization of non-conjugated diene hydrocarbons, 4) dehy- dration arA recombined polymerization, 5) polycondensation on the interface of phases as a chemical method of direct formation of the ready fiber, 6) hydrolytic polymerizati,on, 7) polycoordination using complex compoalds with metals, such as beryllium, obtaining claw-type polymers.

A051/AI29 paper to the characteristics of the most important tasks and directions of scien- tific development, especially physics and physical chemistry, in the field of poly- mer fibers. The properties of these fibers include elastomer fibers with ba? aver- age module, elastic properties, thermal characteristics, non-reversible losses when heated, the molecular weight and the fractional composition. V. A. Kargin and N. V. Mikhaylov calculated the theoretical stability of the maximum-orientated cellulose fibers, which showed valuez of 300 kg/mm2, or about 200 Ian of breaking iength. This theoretical computation is apparently true to some approximation for chemical fibers of any composition. Strength indices have been reached in the la- boratories equalling half of the assumed theoretical limit. V. F. Yevstratov spoke on the demands placed on the future cord for tires. The demands-on future fabrics for the production of rubber articles were discussed by S. Ye. Strusevich. The use of conveyor belts, flat and edge-type belts in production will increase the durabil- ity of articles. Fabrics or threads made of high-index fibers, such as polyether and fortisan, are considered to be advantageous. Hydrate cellulose fibers are in- cluded in this group. Of the polyamide fibers tested, anide and enant were found to be the most suitable for the rubber article industry. FluorIne-containing spe- cial fibers are necessary for heat-resistant articles for temperatures reaching Card 2/3 3/138/61/000/005/006/006 A creative discussion on the perfecting of... A051/A129 3000C and more. A discussion was held with respect to the papers presented In which 17 representattives of various scientific organizations and plants in diffe- rent cities.participated. Lyubimova of the Nauchno-issledovatellskiy institut bumagi (Scientific Research Institute of Paper) (VNIIB) spoke on the methods for improving the quality of cellulose used in the production of' viscose fibers of high modules. Epshteyn spoke on the experimental cordless tires, in which the rubber-resin formulations based on the combinations of high-styrenes aniline-for- maldehyde or other resins, serve as reinforcing layers. N. N. Lintkov and 1. 1. Seleznev supplemented the paper by V. T?. Yevqtratov by analyzing the functioning of the cord thread in the tire. The elongation or the cord thread by 16 - 20% is considerad to be the optimum for tires, but the specific indices are determined by the type of road and the material of the cord thread, F. I. Yashunskaya stated precisely the demands placed on the cord threads. P. F. Bactenkov reported that the volume of scientific research work in the field of.perfecting the fibers for tire cord lags behind the demands for increasing the quality of the tires.
