Abstract
The invention comprises polybutadiene having between 96 and 100% cis-1:4 configuration. This polymer, as well as copolymers-not highly stereospecific-of butadiene with other conjugated dienes are produced by polymerization in a hydrocarbon medium in the presence of a minor amount of catalyst formed by mixing an aluminium alkyl and a halide of nickel or cobalt. The invention also comprises a catalyst wherein the constituents are mixed in the presence of a hydrocarbon diluent; a sulphur-vulcanizable composition comprising carbon black and the cis-1:4-polybutadiene of the invention and a sulphur-vulcanized composition comprising said polybutadiene. The usual aluminium alkyls, hydrocarbon diluents and synthetic rubber composition ingredients are mentioned in the Specification. Reference has been directed by the Comptroller to Specification 826,639.
