THERMOPLASTIC RESIN COMPOSITION

摘要

PURPOSE: A thermoplastic resin composition is provided to ensure excellent scratch resistance, coloring property, impact strength and weather resistance as well as excellent heat resistance. CONSTITUTION: A thermoplastic resin composition includes, based on the total weight portion of the thermoplastic resin composition, (a) 20-60 parts by weight of a first graft copolymer polymerized from aromatic vinyl compounds and vinyl cyanide compounds to a rubber latex; (b) 0.1-40 parts by weight of a second graft copolymer polymerized from (meth)acrylic acid alkyl ester compounds, aromatic vinyl compounds and vinyl cyanide compounds; and (c) 40-80 parts by weight of a third graft copolymer polymerized from (meth)acrylic acid alkyl ester compounds, aromatic vinyl compounds and acid anhydrides.
