Abstract

Graft copolymers are made by polymerizing a monomeric material consisting of acrylonitrile or a mixture of acrylonitrile with up to 15% of another mono-olefinic monomer in an aqueous solution of a preformed copolymer of from 25 to 75% of vinyl pyridine or a C1-C4 alkyl derivative thereof and 75 to 25% of acrylic acid in the presence of a water-soluble peroxy catalyst or an azo catalyst, and then separating the resulting graft copolymer, which is prepared so that it contains from 2 to 10% of the vinyl pyridine in polymeric form. Monomers specified for use in conjunction with acrylonitrile are vinyl acetate, styrene and vinyl and vinylidene chlorides. Catalysts specified are the alkali metal and ammonium persulphates, perborates and percarbonates, which may be used in conjunction with alkali metal and ammonium bisulphites or sodium formaldehyde sulphoxylate, and azodiisobutyronitrile. The polymerization may be carried out in the pressence of mercapto regulators such as tert-dodecylmercaptan and mercaptoacetic acid. The graft copolymers may be dissolved in dimethylacetamide and from such solutions may be prepared films and fibres dyeable with acid dyestuffs. The preparation is described of a copolymer of acrylic acid and 2-methyl-5-vinyl pyridine by a process involving the addition of the monomers to a heated aqueous medium with the simultaneous addition of potassium persulphate and sodium bisulphite.
