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.

Abstract: A plurality of corona-treated polymeric films, and metal foils or sheets, are alternately arranged and laminated together to form a laminate suitable for e.g. insulating panels.

At sufficient thicknesses, the sheet can be stamped or shaped. Both outermost surfaces of the laminate can comprise polymeric film, or both surfaces can comprise metal foils. Alternatively, one outer surface can be a polymeric film and the other outer surface can be a metal foil.

Either the first or second polymer contains 5 to 75% by weight of a third polymer which is an olefinic polymer having functional groups thereon. Either of the first two polymers may contain up to 90% of the usual additives. This enables the production of such articles with high interface strength.
