摘要： Acrylonitrile is polymerized in aqueous solution containing zinc chloride, hydrogen peroxide and from 0,1 to 10 moles of an oxygen acid of chlorine or metal salt thereof per mole of hydrogen peroxide, the total weight of hydrogen peroxide and acid being from 0,1 to 10% by weight of the monomer. The acrylonitrile may be polymerized alone or in admixture with other monomers such as methacrylic acid, amide, nitrile and esters, acrylic acid, amide and esters, e.g. methyl and butyl acrylates, allyl alcohol, vinyl acetate, itaconic acid, vinyl pyridines, N-vinyl-4-beta-hydroxyethyl-imidazole and ethylene and allyl sulphonic acids and salts thereof. Oxygen acids of chlorine specified are hypochlorous, chlorous, chloric and perchloric. In addition to zinc chloride the aqueous solution may contain other salts, e.g. sodium, ammonium, calcium and magnesium chlorides, or organic compounds, e.g. alcohols, ketones or nitriles. The process is preferably carried out by the continuous addition of the reactants to a vessel in such a way that it is occupied only by the reactants.
