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.
