Abstract: The random, hydrogenated copolymers according to the present invention of unsubstituted conjugated dienes and substituted conjugated dienes, having a glass transition temperature of ??60° C., an enthalpy of fusion of ?100 J/g and a content of residual double bonds in the range from 0 to 80%, are suitable for the production of rubber moldings of all kinds which have good resistance to ageing and high resilience at low temperatures. In particular, various tire components and industrial rubber articles may be mentioned as rubber moldings. The copolymers are also suitable for the rubber modification of brittle thermoplastics.

Abstract: The hydrogenated vinyl-polybutadienes according to the present invention have degrees of hydrogenation of from 20 to 100%, Mooney viscosities in the range of from 10 to 150 Mooney units (ML 1+4/100° C.), glass transition temperatures (Tg) of ??57° C. and enthalpies of fusion (?H) of ?30 J/g and having a microstructure with a) from 0 to 44 wt. % 1,2-vinyl-butadiene units of the formula b) from 20 to 64 wt. % 1,2-butylene units of the formula c) from 0 to 60 wt. % 1,4-butenylene units of the formula CH2—CH?CH—CH2 and d) from 0 to 60 wt. % 1,4-butylene units of the formula CH2—CH2—CH2—CH2 are outstandingly suitable for the production of rubber molded bodies of any kind, especially for the production of industrial rubber articles and of tires and tire components. The rubber molded bodies produced from the hydrogenated vinyl-polybutadienes according to the present invention have good resistance to ageing and good elasticity at low temperatures.
