Abstract: A metal member—polyarylene sulfide resin member complex superior in airtightness between the metal member and the polyarylene sulfide (PAS) resin member and a production method therefor, in which the complex comprises a metal member and a PAS member combined together into a one-piece shaped article by injection molding and satisfies conditions 1) and 2) as described, and the PAS resin member contains a PAS resin and a modified ethylene copolymer.

Abstract: A process for producing a succinimide resin composition is provided which comprises reacting a maleic anhydride-olefin type copolymer constituted of 40-60 mol % of maleic anhydride units, 60-40 mol % of olefin units, and 0-20 mol % of a copolymerizable monomer units with one or more amine compounds for imide formation in the presence of a second polymer other than the succinimide resin. This process improves the productivity by lowering the torque in the extrusion reaction, giving a succinimide copolymer resin composition having low yellowness and high transparency with high production efficiency.
