Abstract

1,170,963. Vinyl chloride polymerization. PRODUITS CHIMIQUES PECHINEYSAINT-GOBAIN. 16 Jan., 1967 [19 Jan., 1966; 30 Nov., 1966], No. 2224/67. Heading C3P. Vinyl chloride is polymerized or copolymerized in aqueous suspension or emulsion in the presence of a seeding product which provides the only catalyst used, is obtained using a waterinsoluble catalyst, and from which unreacted monomers have been removed. The seeding product is prepared in suspension in the presence of polyvinylalcohol, methylcellulose, carboxycellulose or gelatine to give a product of particle size 20-200 microns and the preparation is repeated as many times as necessary to provide a sufficient amount for the subsequent polymerization. Alternatively it is prepared in suspension in the presence of an alkylarylsulphonate, alkylsulphate or fatty acid salt of an alkali metal optionally with an added fatty alcohol or polyoxyethylene alkylphenol to obtain a product of particle size 0À05-1À5 microns. The catalyst is lauroyl peroxide, tertiary butyl diethylperacetate, diethylhexylpercarbonate or diacetylperoxide. The polymerization is preferably effected continuously passing monomer or monomer mixture, seeding product, water and dispersing agent into a reaction mixture and removing product continuously.
