Abstract

A polymer blend comprises from 50 to 98 parts of anhydrously polymerized rubbery 1-4-polybutadiene and from 2 to 50 parts of a 1-2 configuration liquid diene polymer and/or a vulcanisate therefor. The rubbery polymer may be produced by the use of alfin catalysts, lithium metal or organo-lithium catalysts, or chromium oxide fixed bed polymerization. It is preferred that the rubbery polymer has a Mooney viscosity (ML4-100 DEG C.) of from 30 to 100 and that at least 85% has the cis-1.4-configuration. The liquid diene polymer preferably has a number average molecular weight of from 1,000 to 20,000 and may be a homo-polymer of butadiene or a copolymer thereof with an aromatic hydrocarbon monomer containing a single vinyl group. The vulcanisate may be prepared using an element or compound thereof from Group VIa preferably in the presence of an accelerator. Fillers, e.g. carbon black may also be present.
