Abstract

Vinyl chloride polymers and copolymers, e.g. with vinyl acetate, are obtained by polymerization in aqueous suspension in the presence of the sodium salt of a copolymer of styrene and maleic anhydride preferably with a mol. ratio 1:1 as suspension stabilizer and in the presence as catalyst of a mixed anhydride of an organic sulpho-per-acid with a carboxylic acid, preferably acetyl-cyclohexane-sulphonyl peroxide. The amount of catalyst may be as low as 0.05 per cent based on the monomers; the ratio of monomers to water may be greater than 1:1; and the products may be in the form of small beads.
