Abstract: 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 1×104 to 5×104, and a stabilizer. In Formula (A), R1 is 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 R2 to R7 are 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.

Abstract: 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.

Abstract: A method of packaging a particle-like material includes: creating a state where an inert gas introduction pipe and an inert gas exhaust pipe being inserted into an airtight container, and where the airtight container being filled up with a particle-like material, and then temporarily closing the opening portion; introducing an inert gas through the inert gas introduction pipe into the airtight container, and discharging the inert gas introduced into the airtight container out through the inert gas exhaust pipe, to thereby replace the inside of the airtight container with the inert gas; and, removing the inert gas introduction pipe and the inert gas exhaust pipe out from the airtight container, and then closing the opening portion of the airtight container.
