Abstract

1459356 Production of vinyl chloride polymers KANEGAFUCHI CHEMICAL INDUSTRIES CO Ltd and LION FAT & OIL CO Ltd 29 Nov 1974 [18 Dec 1973] 51913/74 Addition to 1398216 Heading C3P A paste-forming vinyl chloride polymer is prepared by polymerizing vinyl chloride or a mixture of vinyl chloride and a minor amount of one or more copolymerizable monomers, in the presence of water and one or more emulsifying agents obtained by sulphonating a C 8 to C 20 alpha-olefin, followed by hydrolysing under alkaline conditions. In the examples, vinyl chloride is homopolymerized and copolymerized with vinyl acetate using emulsifiers comprising the sodium salts of a C 12 - and a C 14 -alpha olefin which has been sulphonated. The polymers produced may be formed into pastes and plastisols in the usual manner, by mixing with plasticizers and other conventional materials.
