Abstract
Disclosed is a thermoplastic resin composition formed by melt-kneading at a temperature of 300.degree. to 340.degree. C. a composition comprising (a) 10 to 95% by weight of a polyphenylene sulfide resin; (b) 90 to 5% by weight of a crystalline resin composed mainly of 3-methyl-1-butene, each of the amount of the components (a) and (b) being based on the sum of the components (a) and (b); (c) 5 to 20 parts by weight per 100 parts by weight of the sum of the components (a) and (b) of a partially hydrogenated alkenyl aromatic compound-conjugated diene copolymer; and (d) up to 150 parts by weight per 100 parts by weight of the sum of the components (a) and (b) of a fibrous filler. In this composition, the poor moldability of the polyphenylene sulfide resin is improved and the poor rigidity at a high temperature of the 3-methyl-1-butene polymer is improved, and excellent heat resistance, chemical resistance and mechanical strength inherently possessed by both the resins are retained.
