THERMOPLASTIC RESIN COMPOSITION AND USE THEREOF

摘要

Disclosed is a thermoplastic resin composition comprising (A) an aromatic polyamide comprising dicarboxylic acid units comprising 50-100 mol% of units derived from terephthalic acid, and 0-50 mol% of units derived from an aromatic dicarboxylic acid other than terephthalic acid and/or an aliphatic dicarboxylic acid having 4-20 carbon atoms, and diamine units derived from an aliphatic diamine and/or an alicyclic diamine, said aromatic polyamide having an intrinsic viscosity of 0.5-3.0 dl/g as measured in conc. sulfuric acid at 30.degree.C and a melting point of higher than 300.degree.C, (B) a graft modified .alpha.-olefin polymer, and/or a graft modified aromatic vinyl hydrocarbon/conjugated diene copolymer or hydrogenated product thereof, and (C) an aliphatic polyamide, wherein said thermoplastic resin composition comprises 10-80 parts by weight of the graft modified .alpha.-olefin polymer, and/or the graft modified aromatic vinyl hydrocarbon/conjugated diene copolymer or hydrogenated product thereof (B) and 5-80 parts by weight of the aliphatic polyamide (C), based on 100 parts by weight of the aromatic polyamide (A).
