Abstract: Polymeric compositions having improved flame retardance properties are disclosed. The compositions comprise a cross-linkable polycarbonate resin having a photoactive group derived from a benzophenone, a bromine source, and optionally a non-brominated and non-chlorinated flame retardant. The composition contains a minimum amount of bromine. Articles formed from the compositions have robust flame retardance properties and enhanced chemical resistance.

Abstract: In an embodiment, a polycarbonate composition comprises: polycarbonate; 7 wt % to 20 wt % titanium dioxide, based upon a total weight of the polycarbonate composition; an optional flame retardant; and an optional UV stabilizer. A plaque formed from the polycarbonate composition has a reflectance of greater than or equal to 95%, as determined by reflectance measurements using a Gretag Macbeth Coloreye spectrophotometer (D65 light source, 10 degree observer, UV included) made at a wavelength of 680 nm. In an embodiment, a polycarbonate composition comprises: a polycarbonate; 7 to 20 wt % titanium dioxide; a flame retardant; and an optional UV stabilizer; wherein the polycarbonate composition has a maximum reflectance of greater than or equal to 95%. The melt volume rate as determined at 300° C. using a 1.2 kilogram weight, in accordance with ASTM D1238-04 is from 5 to 30 grams per 10 minutes.

Abstract: Polymeric blends having improved flame retardance properties and good ductility at low temperatures are disclosed. The blend is formed from (A) a photoactive additive containing a photoactive group derived from a monofunctional benzophenone; and (B) a polymer resin which is different from the photoactive additive. The additive can be a compound, oligomer, or polymer. When exposed to ultraviolet light, crosslinking will occur between the photoactive additive and the polymer resin, enhancing the chemical resistance and flame retardance while maintaining ductility.
