Abstract

Process for preparing chemically unitary acrylonitrile-vinyl chloride copolymers, with improved degree of whiteness, composed of 25 to 60% by weight of acrylonitrile and 40 to 75% by weight of vinyl chloride and, optionally, 15% of further ethylenically unsaturated compounds, copolymerizable, according to the emulsion polymerization procedure, with a Redox catalyst of persulfate and sulfurous acid compound, characterized in that a) the weight ratio between reducing component and oxidizing component amounts to at least 4: 1 and 2) the polymerization is carried out at a pH between 2.5 and 4.
