A polycarbonate resin composition, a molded article, a polycarbonate resin, and an end-capping agent for polycarbonate resins are provided. The polycarbonate resin composition contains: a polycarbonate resin having a terminal structure represented by Formula (A) and having a viscosity average molecular weight from 1&#xd7;10to 5&#xd7;10, and a stabilizer. In Formula (A), Ris selected from the group consisting of a hydrogen atom, halogen atoms, linear alkyl groups having from 1 to 9 carbons, branched alkyl groups having from 3 to 9 carbons, linear alkenyl groups having from 2 to 9 carbons, branched alkenyl groups having from 3 to 9 carbons, and aryl groups having from 6 to 12 carbons; and Rto Rare each independently selected from the group consisting of a hydrogen atom, alkyl groups having from 1 to 9 carbons, and alkoxy groups having from 1 to 9 carbons.

A thin sheet or film excellent in flame retardancy and light-blocking properties is provided. A battery pack case and others with high flame retardancy are each molded from this thin film. A thin sheet or film Including a specific phosphorus-containing flame retardant in a polycarbonate resin is excellent in thickness accuracy, flame retardancy and appearance. A thin sheet or film excellent in flame retardancy and also having a thickness of 0.01 to 0.25 mm was formed when controlling its thickness uniformly during sheet or film molding. Further, upon addition of carbon black, the resulting sheet or film was found to have good light-blocking properties and higher flame retardancy. Moreover, when used as a film packaging material for battery packs, the sheet or film of the present invention was found to be excellent in film strength and ultrasonic weldability.

Flame-retardant sheet or film, products comprising the same and process for production thereof

The present invention provides a deoxidizing multilayered body, which sufficiently suppresses the production of odorous organic components produced by oxidation, and which absorbs oxygen at a fast rate. The present invention relates to the deoxidizing multilayered body that is constituted by laminating at least an isolation layer (A) that contains a thermoplastic resin, an oxygen absorption layer (B) which is made of an oxygen absorbent resin composition (b) that contains an oxidizable thermoplastic resin and a transition metal catalyst, an odor absorption layer (C) which is made of an odor absorbent resin composition (c) that contains a thermoplastic resin and an odor absorbent, and an oxygen barrier layer (D) which contains an oxygen barrier substance, in this order.

Deoxidizing multilayered body

The present invention provides a deoxidizing multilayered body, which sufficiently suppresses the production of odorous organic components produced with oxidation, and which absorbs oxygen at a fast rate. The present invention is the deoxidizing multilayered body that is constituted by laminating at least an isolation layer (A) that contains a thermoplastic resin, an odor absorption layer (B), which is made from an odor absorbent resin composition (b) that contains an oxidizable thermoplastic resin, a transition metal catalyst, and an odor absorbent, an oxygen absorption layer (C), which is made from an oxygen absorbent resin composition (c) that contains an oxidizable thermoplastic resin and a transition metal catalyst, and an oxygen barrier layer (D), which contains an oxygen barrier substance, in this order.
