Abstract
Interpolymers of a monomeric mixture comprising at least two conjugated diolefines and styrene, in which the styrene is present in an amount of from 3-25 weight per cent based on the interpolymer, are made by effecting the copolymerization in the presence of an Alfin catalyst consisting essentially of a sodium alkoxide, a sodium alkenyl compound, and an alkali metal halide, and as molecular weight modifier one or more dihydro aromatic hydrocarbons, e.g. 1,4-dihydrobenzene. The interpolymer has a molecular weight of from 50,000 to 1,250,000. The dienes may be selected from butadiene, isoprene, piperylene, 2,3-dimethyl-1,3 - butadiene, 3 - furyl - 1,3 - butadiene, and 3 - methoxy - 1,3 - butadiene. Other monomers such as alkyl styrenes, methoxy styrenes, vinyl naphthalene, vinyl ethers and vinyl furane may also be present. The copolymerization and recovery is carried out by known techniques. The interpolymer may be vulcanized by conventional methods.
