THERMOPLASTIC RESIN COMPOSITION HAVING GOOD WEATHERABILITY AND SCRATCH RESISTANT PROPERTY

摘要

A thermoplastic resin composition is provided to improve weather resistance and scratch resistance without the deterioration of fluidity, tensile strength, color and thermal stability. A thermoplastic resin composition comprises 100 parts by weight of a base resin which comprises 20-50 parts by weight of an acrylonitrile-butadiene-styrene-based graft copolymer and 10-80 parts by weight of an acrylate-styrene-acrylonitrile-based terpolymer; 0.2-1.0 parts by weight of a high viscosity silicone resin; and optionally 30 parts by weight or less of a styrene-acrylonitrile-based copolymer. Preferably the styrene-acrylonitrile-based copolymer comprises 30-90 parts by weight of a styrene-based monomer and 10-70 parts by weight of an acrylonitrile-based monomer.
