PURPOSE:To obtain the titled composition outstanding in both color tone and mechanical strength, suitable for electric and electronic parts especially connectors, etc., by blending specific polyphenylene sulfide resin, glass fiber, inorganic filler and pigment in each specified amount. CONSTITUTION:The objective composition can be obtained by blending (A) 80-30wt% of a polyphenylene sulfide resin (a copolymer from p-dichlorobenzene and trichlorobenzene) prepared by rinsing and extraction of an uncrosslinked polyphenylene sulfide resin having a melt viscosity (at 300 deg.C) 30-100Pa.s at a shear rate 500sec<-1> with an organic solvent (e.g. acetone) to such a point as to be <=1wt% in the oligomer content, (B) 10-50wt% of glass fiber (e.g. chopped strand with a diameter 20-5mu), (C) 0-40wt% of inorganic filler with an average particle size 30-1mum (e.g. calcium carbonate) and (D) 0.1-5wt% of pigment (e.g. titanium dioxide). |
