Title: Polycarbonate resin compositions comprising cyanacrylic acid ester stabilizer compounds

Abstract: Improved polycarbonate resins are prepared comprising specific amounts of a cyanacrylic acid ester type UV absorber in combination with a synergistic phosphite type stabilizer and, optionally, a hindered phenol type stabilizer and/or a lactone type stabilizer. The polycarbonate compositions according to the invention can be used to prepare molded, shaped or otherwise fabricated articles having improved combinations of protection against UV radiation, color and color stability with reduced plate-out behavior during processing. The compositions are especially suitable for use in extrusion, blow molding, thermoforming, injection molding, injection blow molding, injection compression molding, film blow molding and foaming processes and provide improved parts or articles.
