  • Thermoplastic polycarbonate compositions, method of manufacture, and method of use thereof
    Publication number: 20070135569
    Abstract: A thermoplastic composition comprising in combination an aliphatic/aromatic co-polycarbonate component; an impact modifier; and a rigid copolymer, and optionally a polycarbonate component and/or a polycarbonate-polysiloxane copolymer is disclosed. The co-polycarbonate comprises repeating carbonate units and repeating aliphatic units. The compositions have a significantly improved balance of properties, including melt flow and impact.

  • Thermoplastic polycarbonate compositions, articles made therefrom and method of manufacture
    Publication number: 20060142486
    Abstract: A thermoplastic composition made from a polycarbonate resin, bulk polymerized ABS, and a polycarbonate-polysiloxane copolymer, wherein a 4-mm thick molded INI bar comprising the composition has an initial (before aging) notched Izod impact strength of at least about 36 kJ/m2 determined in accordance with ISO 180/1A at ?40° C. An article may be made from such a composition. The article may be formed by molding, shaping or forming the composition to form the article.

  • Thermoplastic polycarbonate compositions, method of manufacture, and method of use thereof
    Publication number: 20060004154
    Abstract: A thermoplastic composition comprising in combination a polycarbonate component; and an impact modifier composition wherein the components of the impact modifier composition are substantially free of a species that degrades a polycarbonate, the components comprising a bulk polymerized ABS; and an impact modifier different from the ABS. The compositions have significantly increased hydrolytic stability, in combination with good thermal stability and/or impact strength.
