Patent ID: 8097680

Claim:
A low gloss thermoplastic resin that can have heat resistance and impact strength prepared by copolymerizing about 5 to about 20% by weight of a conjugated diene rubber (A), about 0.5 to about 8% by weight of an aromatic rubber copolymer (B), about 15 to about 29% by weight of a heat resistant aromatic vinyl compound (C), wherein said heat resistant aromatic vinyl compound (C) is α-methyl styrene, about 10 to about 50% by weight of an aromatic vinyl compound (D), about 10 to about 30% by weight of an unsaturated nitrile compound (E) and about 0.005 to about 0.2 parts by weight of a cross linking agent (F), based on the total weight of the thermoplastic resin.
