  • Patent number: 8466225
    Abstract: An aromatic polycarbonate resin composition including 100 parts by mass of a polycarbonate resin (A) containing an aromatic polycarbonate resin (a-1) and/or a silicone-copolymerized polycarbonate (a-2), and 0.01 to 30 parts by mass of a nanoporous carbon (B). A molded body of the resin composition is also provided. The aromatic polycarbonate resin composition has improved flame retardancy, moisture resistance and stability at a high temperature molding stage because of the addition of the nanoporous carbon to the polycarbonate resin containing an aromatic polycarbonate and/or a silicone-copolymerized polycarbonate, and is suitably used as, for example, a casing for OA appliances, electric and electronic appliances or communication appliances.

  • Patent number: 7994239
    Abstract: Provided is an aromatic polycarbonate resin composition including a combination composed of 98 to 1 mass % of an aromatic polycarbonate (A), 1 to 98 mass % of an aliphatic polyester (B), and 1 to 80 mass % of an organic filler derived from a natural product (C), the aromatic polycarbonate resin composition being obtained by suppressing increase in density of an aromatic polycarbonate resin composition containing an aliphatic polyester, while improving rigidity and fluidity thereof and ameliorating poor external appearance such as pearly luster.
