Abstract
Am impact modifier comprising a blend of 100 parts by weight of a graft copolymer (A) obtained by graft-polymerizing in a single or more stages a monomer or monomer mixture consisting of 95 to 100% by weight of at least one monomer selected from the group consisting of alkyl acrylates, alkyl methacrylates, aromatic vinyl compounds and vinyl cyanide compounds and 0 to 5% by weight of a polyfunctional crosslinking agent on an acrylic elastomer mainly composed of an alkyl acrylate and containing 0.1 to 5% by weight of a polyfunctional crosslinking agent and/or a butadiene elastomer composed of a polybutadiene or a copolymer of 50% by weight or more of a butadiene and 50% by weight or less of other vinyl compound copolymerizable therewith and containing 0 to 5% by weight of a polyfunctional crosslinking agent, and 0.1 to 20 parts by weight of a copolymer (B) obtained by copolymerizing 3 to 30% by weight of an unsaturated acid monomer and 97 to 70% by weight of a vinyl monomer copolymerizable therewith, and a thermoplastic resin composition having high impact resistance and excellent moldability and workability comprising 3 to 50 parts by weight of the modifier set forth above and 100 p…
