    摘要: 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.

    摘要: This invention relates to a process for the production of polydienes having controlled Mooney viscosity, carried out by means of catalysts based on rare earth compounds, which is characterized in that the conjugated dienes used are polymerized in the presence of from 0.005 to 80 wt. % of 1,2-dienes, based on the sum of conjugated dienes used and of 1,2-dienes used. The polydienes thus produced are used particularly in the manufacture of car tires.
