摘要： Thermoplastic compositions include a polycarbonate-siloxane copolymer comprising: from about 49.5 wt % to about 97.95 wt % of at least one polycarbonate polymer; from about 2.0 wt % to about 49.5 wt % of at least one polycarbonate-siloxane r copolymer; and from about 0.05 wt % to about 1.0 wt % of at least one release agent. The composition exhibits a melt volume flow rate of at least about 25 cm3/10 min, a ductile/brittle transition temperature of less than or equal to 10° C., and high gloss after metallization and/or a substantial tensile yield strength retention improvement when exposed to sunscreen. Methods of forming an article include: forming a mixture comprising the thermoplastic composition, and injection molding, extruding, rotational molding, blow molding or thermoforming the mixture in a mold to form the article. Such compositions and methods may be used to form articles including, but not limited to, automotive bezels and housings in consumer devices.

摘要： A reinforced resin composition may include a polycarbonate, a functionalizing agent, and an inorganic filler that has been functionalized with the functionalizing agent, the functionalized inorganic filler being present in an amount ranging from 1 to 25 percent by weight of the resin composition. The reinforced resin may exhibit a melt flow index of 25 or less, when measured at a load of 1.2 kg, after allowing the resin to remain at a temperature of 300° C. for 10 minutes. A method of reducing thermal degradation of a reinforced polycarbonate material may include introducing into said polycarbonate material at least one inorganic filler functionalized with a functionalizing agent, such that the reinforced resin exhibits a melt flow index of 25 or less, when measured at a load of 1.2 kg, after allowing the resin to remain at a temperature of 300° C. for 10 minutes.
