  • THERMOPLASTIC COMPOSITION AND USE FOR LARGE PARISON BLOW MOLDING APPLICATIONS
    Publication number: 20100316823
    Abstract: A polymeric blend composition, and method of using same for large parison blow molding applications, comprising greater than about 50 parts by weight of a carbonate polymer component (e.g., a branched polycarbonate having a weight average molecular weight (Mw) of about 28,000 to about 36,000); and less than about 50 parts by weight of an acrylonitrile-butadiene-styrene (ABS) component, the ABS component including a styrene acrylonitrile (SAN) phase including acrylonitrile (e.g., in an amount greater than 25 percent by weight of the SAN phase); and a butadiene-based rubber particle phase, wherein at least a portion of the butadiene-based rubber particle phase includes butadiene grafted with SAN.
    Type: Application
    Filed: January 28, 2009
    Publication date: December 16, 2010
    Applicant: Dow Global Technologies Inc.
