Abstract
A glass fiber-reinforced thermoplastic resin excellent in providing a balance between processability, tapping strength and heat resistance. The composition comprising (A) 10 to 60% by weight of a terpolymer which comprises N-phenylmaleimide, styrene and acrylonitrile, (B) 5 to 20% by weight of a graft polymer which comprises at least one rubber selected from the group consisting of a conjugated diene rubber, an ethylene-propylene rubber and an ethylene-butylene rubber comprising ethylene and butylene, to which rubber styrene and acrylonitrile are graft polymerized, (C) 10 to 80% by weight of a copolymer which comprises styrene and acrylonitrile, and (D) 5 to 35% by weight of glass fiber, wherein (a) the terpolymer has an intrinsic viscosity of 0.20 dl/g to 0.70 dl/g, (b) the copolymer has an intrinsic viscosity of 0.40 dl/g to 1.00 dl/g, (c) the intrinsic viscosity of terpolymer is equal to or smaller than that of the copolymer, and (d) a styrene content in the copolymer minus a styrene content in the terpolymer is from +20 to -5% by weight.
