Abstract

A butadiene-1 : 3 hydrocarbon or a halogen derivative thereof and a vinyl benzene are copolymerized in the presence of a minor proportion, e.g. 0.5 per cent to 5 per cent of a drying oil, e.g. tung, perilla, linseed or oiticica oils. The butadiene hydrocarbon may be butadiene itself, isoprene, dimethyl butadiene or chlor-butadiene. The vinyl benzenes are those described in U.S.A. Specification 1,938,731, e.g. styrene itself, divinyl benzene and a -methyl styrene. The polymerization may be conducted in aqueous emulsion containing a stabilizing agent, a catalyst and a promoter. In an example, water, sodium perborate, decyl benzene sodium sulphonate, styrene, benzoyl peroxide, butadiene, carbon tetrachloride and tung oil were charged into a rotating iron autoclave and heated at 70 DEG C. for 3 days, after which the emulsion was coagulated by addition of alcohol. A vulcanizable composition may be prepared from the product by the addition of zinc oxide, whiting, sulphur, dibenzothiazyl-thiol-dimethylurea, diphenyl-guanidine and stearic acid.
