These assets include the production of various types of synthetic rubber used to produce high-quality tyres by leading Russian and world manufacturers; production of MTBE, butadiene, isoprene and other intermediate products, as well as the infrastructure of the industrial park, in which territory of there is a number of chemical and other technology companies operating.
Key statement: The subject invention is directed towards tire components comprising rubber compositions comprising (1) about 2 phi- to about 45 plir of a trans1,4-isoprene-butadiene copolymer which has about 4 weight percent to about 16 weight percent butadiene repeat units aid from about 84 weight percent to about 96 weight percent isoprene repeat units, wherein the trans-1,4-isoprene-butadiene copolymer has a Mooney ML 1+4 viscosity which is within the range of about 35 to about 80; and (2) about 55 phr to about 98 phr of at least one other elastomer, preferably a diene based elastomer.
