THERMOPLASTIC RESIN COMPOSITION AND A RESIN MOLDING CAPABLE OF IMPROVING LOW-TEMPERATURE STRESS BLOOMING RESISTANCE AND SCRATCH RESISTANCE WITHOUT USING POLYORGANOSILOXANE

摘要

PURPOSE: A thermoplastic resin composition and a resin molding are provided to improve scratch resistance, surface hardness, mechanical property, and especially low temperature internal stress blooming resistance.;CONSTITUTION: A thermoplastic resin composition comprises 100.0 parts by weight of base resin and 0.01-5 parts by weight of (C1-10 alkyl)acrylate based polymer. The base resin comprises 70-90 parts by weight of polymerized acrylic resin and 10-30 parts by weight of graft copolymer. The graft-copolymer is a polymer of conjugated diene-based rubber polymer, vinyl cyanide compound, and aromatic vinyl compound. The Acrylic resin is a polymer of ester-based compound, vinyl cyanide compound, and vinyl aromatic compounds. The ester based compound is one or more of (C1-6 alkyl)acrylate, (C1-6 alkyl)methacrylate, and (C1-6 alkyl)ethacrylate.;COPYRIGHT KIPO 2012
