FIELD: chemistry of polymers, chemical technology.
SUBSTANCE: invention relates to a method for preparing thermoplastic polyvinyl chloride molding composition modified with the impact viscosity elastomer-containing modifying agent with improved impact-strength, resistance against bending and improved optical properties by using the impact viscosity modifying agent. Impact viscosity modifying agent consists of core and envelope wherein a core consists of polyvinyl chloride or vinyl chloride copolymer, and an envelope consists of crossed-linked homo- or copolymer of alkylacrylate or alkylmethacrylate. A modifying agent is prepared by emulsion polymerization for two stages wherein at the first stage a core is prepared and at the second stage an envelope is prepared in the presence of a core. Vinyl chloride monomer is subjected for the grafting co-polymerization by suspension method in the presence of indicated impact viscosity modifying agent.
EFFECT: improved preparing method.
