Abstract

1510714 Copolymerization of acrylonitrile and vinyl chloride using redox catalysts BAYER AG 20 Aug 1975 [22 Aug 1974] 34574/75 Heading C3P Acrylonitrile-vinyl chloride copolymers of improved whiteness comprising 25-60% by wt. of acrylonitrile and 75-40% by wt. of vinyl chloride and optionally up to 15% by wt. of at least one other copolymerized ethylenically unsaturated compound are obtained by emulsion polymerization of the monomers at pH 2À5-4 in the presence of a redox catalyst system comprising a persulphate as oxidizing component and a water-soluble compound of sulphur (IV) as reducing components the ratio by weight of reducing component to oxidizing component being at least 4 : 1. In the examples the persulphate is ammonium persulphate, and the reducing component is sodium or potassium sulphite. [GB1510714A]
