  • Patent number: 5160786
    Abstract: A resin material for inserting a lead frame comprises:(A) 100 parts by weight of a polyarylene sulfide resin,(B) 0.1 to 30 parts by weight of an .alpha.-olefin copolymer graft-copolymerized with an unsaturated carboxylic acid or its anhydride, and(C) 10 to 300 parts by weight of a fibrous filler, a nonfibrous inorganic filler or a mixture thereof.The grafted unsaturated carboxylic acid such as maleic anhydride is essential, in comparison with olefin copolymers, preferably in an amount of 1 to 5 percent. The olefin copolymer includes that of ethylene and ethyl acrylate. The addition of (B) effectively works to improve adhesion between the lead frame and the polyarylene sulfide composition, because it does not decompose and give a gas during molding. Heat resistance and the molding performance does not change. An example comprises PPS, a copolymer of ethylene and ethyl acrylate, grafted with 3.0% of maleic anhydride, glass fiber and glass beads.
