Abstract

Acrylonitrile is polymerized in solution in dimethyl sulphoxide in the presence of an anionic or free-radical catalyst, other than a peroxide, a portion only of the catalyst being added to the reaction mixture at the start of polymerization, the remainder being added in portions during the course of the reaction. The acrylonitrile may be polymerized alone or in the presence of a minor proportion of another monomer, e.g. allyl alcohol, vinyl acetate, methyl methacrylate, vinyl ethyl ether and 2-vinyl-5-ethyl pyridine. Catalysts specified are ammonium persulphate and azodiisobutyronitrile.
