摘要：
A thermoplastic resin composition which comprises:
(A) 45-90% by weight of a rubber-modified thermoplastic styrene resin in which the grafting degree is 40-150% by weight based on the weight of the rubbery polymer,
(B) 9.5-54.5% by weight of an aromatic polyester having an intrinsic viscosity of 1.1-2 dl/g as measured at 25°C in o-chlorophenol, and
(C) 0.1-20% by weight of a graft copolymer obtained by graft-copolymerizing a monomer mixture consisting of 60-80% by weight of an aromatic alkenyl compound and 20-40% by weight of an alkenyl cyanide compound on a copolymer consisting essentially of an olefin unit and an epoxy group-containing unsaturated compound unit, and (D) optionally a silicone lubricant in a proportion of 5-20,000 ppm of the total weight of the (A), (B) and
(C) components.
Said thermoplastic resin composition can be prepared by previously mixing a part or the whole of the (B) component, a part or the whole of the (C) component and 0-20% by weight of the (A) component, and then mixing the resulting mixture with the remaining component or components.
