  Processes for increasing the chemical resistance of a surface of a formed product are disclosed. The formed product is produced from a polymeric composition comprising a photoactive additive containing photoactive groups derived from a dihydroxybenzophenone. The surface of the formed product is then exposed to ultraviolet light to cause crosslinking of the photoactive additive and produce a crosslinked surface. The crosslinking enhances the chemical resistance of the surface. Various means for controlling the depth of the crosslinking are also discussed.

  Polymeric blends having improved flame retardance properties and good ductility at low temperatures are disclosed. The blend is formed from (A) a photoactive additive that is a cross-linkable polycarbonate resin containing a photoactive group derived from a dihydroxybenzophenone; 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.

  Photoactive additives are disclosed. Such additives are polymers or oligomers that contain UV-active groups (such as ketone groups) and contain polysiloxane blocks as well. When added to a base polymeric resin and used in molding, this structure promotes migration of the additive to the surface. Crosslinking occurs upon exposure to ultraviolet light.
