Abstract: A coextruded moisture resistant polycarbonate article has a relative thin moisture resistant, polyphthalate-carbonate layer adhered to a relatively thick aromatic polycarbonate corelayer. The coextruded article has the high degree of transparency of aromatic polycarbonates and the moisture resistance and haze resistance of polyphthalate-carbonate. Coextruded sheet and film of the present invention may be subsequently thermoformed without losses in the desirable properties thereof.

Abstract: Thermoplastic composites of polycarbonate and siloxane-polycarbonate block copolymer layers are produced by a coextrusion process. The composites are useful for the production of high-strength and impact resistant laminate glazing panels.

Abstract: Disclosed are blends of (a) an aromatic brominated polycarbonate; and (b) a polyphthalatecarbonate. Preferably, the blends also contain an amount of a silicone-polyimide. The blends exhibit good flame resistance and low smoke generation.

Abstract: A method for impregnating at least one surface of an aromatic carbonate resin article with an ultraviolet radiation screener comprising applying a protective masking element to at least one surface of said article, said protective masking element having disposed on the surface thereof which is in contact with said surface of said aromatic carbonate resin article an adhesive layer containing an effective amount of at least one ultraviolet radiation absorber, while said surface of said article is at a temperature sufficiently high for said ultraviolet radiation screener to migrate from said adhesive layer into the surface of said article in ultraviolet radiation screening effective amounts.
