AND THERMOPLASTIC COMPOSITION HAVING IMPACT MODIFIER HAVING CORE-SHELL STRUCTURE

摘要

PURPOSE: A thermoplastic resin composition comprising a graft copolymer having a core-shell structure with high refractivity is provided to ensure excellent appearance property and impact property. CONSTITUTION: A thermoplastic resin composition comprises (A) 100 parts by weight of a polycarbonate resin, (B) 45-55 parts by weight of a rubber-modified aromatic vinyl-based resin, and (C) 10-20 parts by weight of a core-shell graft copolymer. The shell of the core-shell graft-copolymer comprises one or more selected from the group consisting of phenylmethacrylate, cyclohexylmethacrylate, benzylmethacrylate, and phenoxymethacrylate. The core is a rubber polymer in which C4-6 diene rubber, acrylate rubber and silicone rubber monomers are polymerized.
