    Abstract: PROBLEM TO BE SOLVED: To provide a flame-retarding thermoplastic resin composition excellent in flame-retardancy, moldability and heat resistance, and also to provide a molded product of the above composition. SOLUTION: The flame-retarding thermoplastic polymer composition comprises: (a) at least one kind of a block copolymer selected from block copolymers having a polymer block A consisting mainly of an α-methylstyrene unit and a polymer block B consisting of a conjugated diene unit and its hydrogenated product; (b) a polyolefin-based resin; and (c) a metal hydrate. The amount of the polyolefin-based resin (b) is 20-600 pts.mass for 100 pts.mass of the block copolymer (a) and the amount of the metal hydrate (c) is 50-300 pts.mass for 100 pts.mass of the total amount of the block copolymer (a) and the polyolefin-based resin (b).

    Abstract: PROBLEM TO BE SOLVED: To provide a resin processed article for arc extinguishment excellent in uninflammability, with little contribution to inner pressure rise, capable of generating thermal decompression gas enabled to efficiently extinguish arc generated at circuit break, and endowed with heat resistance standing temperature rise as well as pressure resistance standing the inner pressure rise at that time, and to provide a circuit breaker using the same.
    SOLUTION: The circuit breaker is provided with a fixed contactor 5 with a fixed contact point 7, a movable contactor 1 with a movable contact point 6, and an arc-extinguishing device for extinguishing arc generated when the fixed contactor 5 and the movable contactor 1 make a switching operation. For the arc-extinguishing device, the resin processed article for arc extinguishment 13 is used made by molding and giving radiation crosslinking on a resin composition containing polyolefin resin (A) with a part of hydrogen atoms of methylene chain substituted with a hydroxyl group and containing 0.2 to 0.7 mol of the hydroxyl group to 1 mol of a methylene group, a micro capsule (B) containing water as a core material, and a reactive organophosphorus flame retardant (C) containing a terminal unsaturated bond.
