Abstract

Process for the preparation of poly (vinyl chloride) or copolymers of vinyl chloride with reduced molecular weight by mass polymerization of vinyl chloride, or of vinyl chloride and a comonomer, using water-soluble Redox systems at temperatures between 0 and -60ºC in the presence of customary lower aliphatic alcohols for this purpose, in amounts of 8-20% by weight, based on the monomers, characterized in that the polymerization is carried out in the presence of cyclic olefins with one or more double bonds, optionally containing as substituents alcohol radicals with 1 to 10 carbon atoms, aryl radicals, aralcohyl radicals, aldehyde groups or alcoholic radicals, and whose total amount amounts to 0.1-10% by weight, preferably 0.5-2% in weight, referring to monomers.
