FIELD: chemistry.
SUBSTANCE: invention relates to a method for graft vinyl chloride copolymers production by emulsion polymerization, to mixtures derived from graft vinyl chloride copolymers, and to a product obtained using the graft copolymers of the invention or mixtures thereof. The method for graft vinyl chloride copolymer production includes obtaining a basis for grafting by monomers polymerization, copolymer phase grafting to the substrate by emulsion polymerization and graft vinyl chloride copolymer extraction. The glass transition temperature of the substrate must be lower than the glass transition temperature of the graft copolymer phase. The said basis for grafting is non-crosslinked, and the said graft copolymer phase is crosslinked.
EFFECT: graft vinyl chloride copolymers are obtained without addition of external plasticizer, which can be used for production of transparent films and moulded articles.
