THERMOPLASTIC RESIN COMPOSITION CONTAINING GLASS FIBER

Document Type and Number:

WIPO Patent Application WO/1993/020142

Kind Code:

A1

Abstract:

A thermoplastic resin composition containing glass fibers, which is excellent in the balance between processability and tapping strength and in the thermal resistance, comprises: A) 10-60 wt.% of a terpolymer composed of N-phenylmaleimide, styrene and acrylonitrile, B) 5-20 wt.% of a graft polymer prepared by grafting styrene and acrylonitrile onto at least one rubber selected from among a conjugated diene rubber, an ethylene/propylene rubber and an ethylene/butylene rubber, C) 10-80 wt.% of a copolymer composed of styrene and acrylonitrile, and D) 5-35 wt.% of glass fibers, and satisfies the following conditions: a) the terpolymer has an intrinsic viscosity of 0.20 to 0.70, b) the copolymer has an intrinsic viscosity of 0.40 to 1.00, c) the intrinsic viscosity of the terpolymer is less than or equal to that of the copolymer, and d) the styrene content of the copolymer minus that of the terpolymer ranges from +20 to -5.
