Abstract
Copolymers of acrylonitrile and preponderant amounts of vinylidene chloride are prepared by copolymerizing the monomers in aqueous emulsion in the presence of 0.5 to 10% by weight, based on the total monomer, of dimethyl formamide. A minor proportion of one or more other monomers, e.g. vinyl sulphonic acid, acrylic acid or maleic anhydride, may also be present, and polymerization may be effected in the presence of hydrogen peroxide or potassium persulphate, or mixtures thereof with formaldehyde sulphoxylate, sodium bisulphite or ascorbic acid; and emulsifiers, e.g. alkali metal salts of sulphonic and fatty acids. In an example, vinylidene chloride, acrylonitrile and acrylic acid are copolymerized in an aqueous medium in the presence of potassium persulphate, ethylhexyl thioglycollate, sodium bisulphite and dimethyl formamide to give a copolymer readily soluble in toluene/methyl ethyl ketone mixtures.
