Abstract

Quaternary ammonium salts of vinyl sulphonic acid (0,1 to 10%) may be copolymerized with 99,9-90% of other ethylenically unsaturated polymerizable compounds in aqueous dispersion free from emulsifier and in otherwise conventional manner. Examples specify the polymerization of trimethylphenylammonium vinyl sulphonate, trimethylcyclohexyl ammonium vinyl sulphonate, the quaternary ammonium salts prepared by reacting triethanolamine and methyl vinyl sulphonate and reacting methyl vinyl sulphonate with the reaction product of 1 mol. of diethylamine and 4 mols. of ethylene oxide. The other unsaturated monomers may be vinyl acetate, vinyl propionate, ethyl acrylate, n-butyl acrylate or vinylidene chloride. The initiator system may be potassium persulphate or potassium persulphate/sodium pyrophosphate. Many other monomers and initiator systems are mentioned.
