Abstract

A rubber composition comprises a high molecular weight elastomeric homopolymer or copolymer consisting of a C4- and/or C5-conjugated dioefin having an intrinsic viscosity in the range 1.5 to 20 and a cis 1-4-content of at least 85% together with a low molecular weight homopolymer or copolymer consisting of a C4-and/or C5-conjugated diolefin having an intrinsic viscosity in the range of 0.1 to 10, the weight ratio between high and low molecular weight polymers being from 95 to 5 to 70 to 30, Isoprene and butadiene are preferred monomers for both polymers. The low molecular weight polymer may have a cis-1-4 content of at least 80%. The products may be mixed with the usual vulcanization additives and vulcanized.
