POLYARYLENE SULFIDE RESIN COMPOSITION COMPRISING POLYARYLENE SULFIDE RESIN, POLYAMIDE RESIN, FIBROUS FIBER AND ETHYLENE-BUTYLENE BLOCK COPOLYMER

摘要

PURPOSE: Provided is a polyarylene sulfide resin composition which is improved in impact strength, toughness and flowability to enhance injection molding property and the appearance of a molded product. CONSTITUTION: The polyarylene sulfide resin composition comprises 20-70 parts by weight of a polyarylene sulfide resin; 20-40 parts by weight of a polyamide resin; 20-50 parts by weight of a fibrous filler; and 1-20 parts by weight of an ethylene-butylene block copolymer. Preferably the polyarylene sulfide resin is obtained by copolymerizing at least two kinds of aromatic monomers and contains 80 mol% or more of a p-phenylene sulfide repeating unit; the polyamide resin is nylon 6 and/or nylon 66; the fibrous filler is a surface-treated fibrous filler selected from the group consisting of 3-glycidyloxypropyltrimethoxysilane, 3-mercaptopropyltrimethoxysilane, 3-(diethylamino)propyltrimethoxysilane and 3-N-(trimethoxysilylpropyl)polyethyleneimine; and the ethylene-butylene block copolymer contains styrene.
