Abstract

A mixture of a butadiene-1,3 hydrocarbon or a halogen derivative thereof and a vinyl cyanide are polymerized in the presence of a minor proportion, e.g. 0.5 to 5 per cent of a drying oil, e.g. tung, linseed, perilla or oiticica oils. Specified components of the mixture are butadiene, isoprene, dimethyl butadiene or chlorobutadiene and acrylonitrile or methacrylonitrile. In examples: (1) butadiene, acrylonitrile, sodium perborate, tung oil, decylbenzene sodium sulphonate and carbon tetrachloride were emulsified in water and heated in a glasslined rocking autoclave at 70 DEG C. for 70 hours. A rubber-like mass was coagulated by alcohol and boiled in an aqueous solution of sodium bisulphite to destroy the catalyst, washed and dried. Compositions containing the copolymer, "Gastex" (Registered Trade Mark), zinc oxide, sulphur, cyclohexylamino - thio - benzthiazole, diphenyl guanidine, stearic acid and dibutyl phthalate were cured by heating; (2) a similar emulsion containing isoprene in place of butadiene and also benzoyl peroxide was heated at 55-60 DEG C. for 72 hours, coagulated with alcohol and the product washed with alcohol and acetone and finally with water. Compositions containing the copolymer, stearic acid, triphenyl phosphate, sulphur, zinc oxide, dibenzothiazyl thiol, dimethyl urea and diphenyl guanidine were similarly cured. U.S.A. Specification 1,973,000 is referred to.ALSO:A mixture of a butadiene-1,3 hydrocarbon or a halogen derivative thereof and a vinyl cyanide are polymerized in the presence of a minor proportion, e.g. 0.5 to 5 per cent, of a drying oil, e.g. tung, linseed, perilla or oiticica oils.
