Abstract

1524492 Vinyl chloride suspension polymerization SIGMA ITALIANA PRODOTTI CHIMICI SpA 3 Feb 1977 [17 Feb 1976] 4522/77 Heading C3P Vinyl chloride is homo- or copolymerized in aqueous suspension using as suspending agent a partially hydrolysed polyvinyl acetate having a saponification number between 300 and 500, derived from a polyvinylacetate of number average mol. wt. between 10,000 and 30,000. Another suspending agent such as a water-soluble polyvinyl alcohol, or cellulose derivative, may also be present.
