Abstract

Procedure for modifying vinyl chloride polymers, characterized in that vinyl chloride polymer is polymerized with an elastic graft copolymer like rubber of (A) 40 to 70 parts by weight of a monomer mixture of 40 to 60 parts by weight of styrene, 40 to 60 parts by weight of methyl methacrylate and 0 to 10 parts by weight of acrylonitrile on B) from 60 to 30 parts by weight of a copolymer of 70 to 90 parts by weight of butadiene, 10 to 30 parts by weight of styrene, 0 to 10 parts by weight of acrylonitrile and 0 to 2 parts by weight of a crosslinking monomer, having an average particle size of 0.05 to 0.5 um, the graft copolymer having been prepared by emulsion polymerization of a mixture of the monomers (A) in the presence of the copolymer (b) in the form of a latex with the help of a catalyst system, composed of a peroxydisulfate and an alkanolamine and of an emulsifier, which is active at a pH higher than 7, followed by isolation graft copolymer the latex by precipitation with an electrolyte at a pH below 7.
