RUSSIAN SYNTHETIC RUBBER INDUSTRY IN 2013. SOME RESULTS
ABSTRACT
In this report the comparative analysis of Russia's synthetic rubber production in is carried out. The period of analysis is 2007, 2011-2013. The tendencies of Russian production of general purpose rubbers: isoprene, butadiene and styrene (methyl) styrene, butyl rubbers. An increasing share of exports of Russian elastomers in 2013. Leaders in terms of sales for export are the SRS and SKD. There is a gradual increase in the proportion SKD produced using technology «neodymium» catalyst system. The dynamics of production IC some Russian enterprises in 2007-2013. An increase in the production of butyl rubber and halobutyl rubber. Production of butyl (galobutil) rubbers in our country has grown continuously and not only in the period under review, and in 2013 reached 237 900 tons, an increase compared with 2007, almost 52%. But, at the same time, in recent years, while Russian manufacturers are not actively being developed large-scale production of modern stamps «neodymium» polydienes, mortar (modified, branched), styrene-butadiene rubbers, rubber compositions with active and other fillers.
Keywords: synthetic rubber, butadiene rubber, isoprene rubber, styrene-butadiene rubber, butyl rubber, development trends.

TECHNOLOGICAL PARAMETERS OF THE HETEROGENEOUS PROCESS OF BROMOBUTYL RUBBER SYNTHESIS
ABSTRACT
Bromination of butyl rubber as a common technological process is under continuous improvement. One of the problems — reducing operating expenses is solved in this paper. The operating expenses were cut due exclude one technological step — treatment of bromide-rich brines by chlorine gas. The new approach to bromination is based on halogenation of basic grade rubber by bromine water produced by electrochemical way. Results showed that this approach can be taken to attain high grade bromobutyl rubber using chlorine free way.
Keywords: bromobutyl rubber, butyl rubber, synthes, bromination, halogenation.

ONCE AGAIN ON ANHYDROUS DEGASSING SYNTHETIC RUBBER SOLUTION POLYMERIZATION
ABSTRACT
In this article the author continues to discuss the topic, described in [1] on the use of waterless method of degassing mortar rubbers. Discusses additional global practices. Recommended use of cyclohexane as a solvent for the production of SBR and amorphous 1,2-polybutadienes and, especially in case of separation from the solution by degassing anhydrous.
Keywords: Anhydrous degassing, experience of the firm «Koperion» SBR, atactic and syndiotactic 1,2-polybutadiene.

THE INFLUENCE OF ELECTRONIC EFFECTS IN ALKYL HALOGEN ON THE SPEED PARAMETERS OF PROCESS OF COPOLYMERIZING OF ISOBUTYLENE WITH AN ISOPRENE AT THEIR USING AS COCATALYSTS
ABSTRACT
On the basis of the conformities over to law brought before on influence of electronic effects of deputies in alkyl halogen additional studies were undertaken as evaluated by influence of deputies in а alkyl halogen coming from the dipole moment of molecules. A new cocatalyst is found and tested for a chlorous aluminium at the receipt of butyl rubber in laboratory terms.
Keywords: isobutylene, cationic polymerization.

SYNTHESIS, PROPERTIES AND APPLICATION OF THE COMPLEX SALT ε-CAPROLACTAM-N-ISOPROPYL-N'-DIPHENYL-n-PHENILENDIAMINDISTERATE ZINC IN ELASTOMERIC COMPOSITIONS
ABSTRACT
The aim of this work was to study the possibility of using dispractol СКJ obtained in the melt is-caprolactam-N-isopropyl- N′-diphenyl-n-phenylenediamine in rubber compounds.
Unlike conventional methods of synthesis, where, as a rule, as the environment is used organic solvent or water, in this case, the function solvent capable of dispersion ES-40-45 and stearic acid, which form a homogeneous melt with viscosity Brookfield 25-30 SDRs. Temperature synthesis is 135-140°C.
Studies have shown that dispractol СКJ able to increase resistance to thermal-oxidative ageing for a long time. The product is a powder of dark-grey color without odour. Also it will not be compressed during storage.
Keywords: the activator, dispergator, the antiager, prolonging action.
