The present invention relates to a thermoplastic resin composition, more
precisely, a thermoplastic resin composition with enhanced impact
resistance, gloss, weather resistance and scratch resistance, compared
with the conventional thermoplastic resin compositions, by containing an
acrylate-styrene-acrylonitrile (ASA) graft copolymer, an aromatic vinyl
compound and vinyl cyan compound copolymer, an alkyl
methacrylate/aromatic vinyl compound/vinyl cyan compound terpolymer and a
di-block copolymer (aromatic vinyl compound/vinyl cyan compound--alkyl
methacrylate/aromatic vinyl compound/vinyl cyan compound).
