  • Polysiloxane-polycarbonate compositions, method of manufacture, and articles formed therefrom
    Patent number: 8389648
    Abstract: A composition, comprising, based on the total weight of the polymer components in the composition, 1 to 40 wt. % of an aromatic polycarbonate, 30 to 98.8 wt. % of a polysiloxane-polycarbonate block copolymer, and 0.1 to 10 wt. % of a polysiloxane-polyimide block copolymer comprising more than 20 wt. % polysiloxane blocks, based on the total weight of the polysiloxane-polyimide copolymer. The compositions provide articles with low haze, high luminous transmittance, and good hydro-aging properties. The articles can further be formulated to have excellent flame retardance, particularly when KSS is used.
    Type: Grant
    Filed: August 2, 2011
    Date of Patent: March 5, 2013
    Assignee: Sabic Innovative Plastics IP B.V.
    Inventors: Purushotham Adoni, Dibakar Dhara, Sriramakrishna Maruvada, Roopali Rai, Veeraraghavan Srinivasan
