Abstract

PURPOSE: To obtain a polyester resin composition having improved impact strength, a high distortion temperature, and a small warp of a molded article, by blending a polyester resin with glass fibers granulated in the presence of the resin and a flat lamellar inorganic filler.
CONSTITUTION: 100 parts by wt. of a polyester resin, e.g., polybutylene terephthalate, etc. is blended with 1W30 parts by wt., preferably 5W20 parts by wt. of glass fibers having a fiber length not less than 1.5 mm. The resulting blend is molten and kneaded in the extruder, and made into chips. The chips are blended with 5W50 parts by wt., preferably 10W30 parts by wt. based on 100 parts by wt. of the polyester of a flat lamellar inorganic filler, e.g., a glass flake, mica, graphite, talc, etc., and the resulting bend is similarly molten, kneaded, and formed into chips to give a polyester resin composition for molding. The glass fibers, 85 wt.% or more of which have a length of 0.005W0.07 mm. 50 wt.% or more of them have a length of 0.03W0.3 mm. 95 wt.% of the glass fibers and the platy inorganic filler in a weight distribution curve have a Stokes diameter of 0.15W0.07 mm.
