Abstract
A copolymer of a ketone containing two polymerizable double bonds each forming part of a conjugated system with the carbonyl group and a monomer containing one polymerizable double bond is made by dehydrohalogenating a bis-(2-haloalkyl) ketone with a solution of a salt of weak acid in the presence of the monomer and polymerizing the resulting mixture with a polymerization catalyst that is present during at least the latter stages of the dehydrohalogenation. The monomer may contain an ion exchange group. The polymerization may be carried out in bulk, aqueous emulsion, or suspension. The ketone may be the divinyl compound obtained from bis-(2-chloroethyl) ketone or vinyl isopropenyl ketone obtained from 2-chloroethyl, 2-chloroisopropyl ketone. The monomer may be methacrylic acid, methyl methacrylate, or styrene. Cation-exchange groups may be introduced into the copolymer by after-treatment with sulphonic acid-containing compounds and anion-exchange groups by introducing haloalkyl groups into the copolymer with subsequent amination. The salt of a weak acid may be sodium acetate, formate, or citrate. Catalysts mentioned are azo-bis-isobutyronitrile and ammonium persulphate. The emulsifier may be polyvinyl alcohol. The copolymer may be in the form of beads or granules.
