The thermoplastic resin composition having good thermal stability, light stability and impact strength as well as the molded article obtainable therefrom

摘要

A thermoplastic resin composition, comprising:(A) 10 to 99 parts by weight of an epoxy group-containing styrene resin, wherein the epoxy groups styrene resin, containing 5 to 50% by weight of an epoxy group-containing vinyl copolymer (a₁) and 50 to 95% by weight of a rubber-modified styrene copolymer resin (a₂) comprises;(B) 1 to 90 parts by weight of a polyester resin, wherein the polyester resin has a limiting viscosity of from 0.3 to 1.15 dl / g;(C) 0.1 to 10 parts by weight of a cyclohexane dimethanol comprehensive thermoplastic polyester resin per 100 parts by weight of a (a) + (b) base resin;(D) from 0.05 to 2 parts by weight of a hindered phenolic compound per 100 parts by weight of a (a) + (b) base resin;(E) from 0.05 to 4 parts by weight of a phosphite compound per 100 parts by weight of a (a) + (b); and base resin(F) is 0.2 to 6 parts by weight of a compound selected from the group consisting of hals compounds, compounds on benzotriazole and mixtures thereof, per 100 parts by weight of a (a) + (b) base resin.
