Abstract
The present invention relates to flame retardant polycarbonate compositions with improved weathering performance, said compositions comprising one or more cyanoacrylic esters. The invention also relates to methods for improving the flame retardancy and weathering performances of polycarbonate compositions by incorporating cyanoacrylic ester(s). Finally, the invention further relates to articles manufactured from flame retardant polycarbonate compositions comprising cyanoacrylic ester(s).
Claims27
A transparent, fire resistant, polycarbonate composition comprising:
- (a) polycarbonate formulation, and (b) a cyanoacrylic ester.
A method to improve the flame retardance of polycarbonate compositions, said method comprising adding to a polycarbonate formulation from which a polycarbonate composition is produced an amount of a cyanoacrylic ester effective for improving the flame retardance of said polycarbonate composition relative to the flame retardance of the polycarbonate composition without the cyanoacrylic ester.
A method to improve the weathering and flame retardance performance of polycarbonate compositions, said method comprising adding to a polycarbonate formulation from which a polycarbonate composition is produced an amount of a cyanoacrylic ester effective for improving the weathering and flame retardance performance of said polycarbonate composition relative to the weathering performance of the polycarbonate composition without the cyanoacrylic ester.
