THERMOPLASTIC RESIN COMPOSITION IN WHICH THE CLOUDY WHITE PHENOMENON AT A LOW TEMPERATURE IS IMPROVED

摘要

According to the present invention, a thermoplastic resin composition comprises: a core including a rubber polymer; (A) a graft copolymer resin including a shell formed by graft-polymerizing an acrylic alkyl ester monomer or methacrylic acid alkyl ester monomer, an unsaturated nitrile monomer, and an aromatic vinyl monomer onto the surface of the core; (B) a non-grafted copolymer resin including a copolymer obtained by polymerizing an acrylic alkyl ester monomer or methacrylic acid alkyl ester monomer, an aromatic vinyl monomer and an unsaturated nitrile monomer, and a polymer or copolymer obtained by polymerizing an acrylic alkyl ester monomer, a methacrylic acid alkyl ester monomer, or a mixture thereof; and a siloxane-based impact modifier. Thus, the composition of the present invention has excellent impact strength and scratch resistance, and does not exhibit a cloudy white phenomenon at a low temperature.
