Abstract: 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.

Abstract: Different interfacial processes for producing photoactive additives are disclosed. Generally, the photoactive additives are cross-linkable polycarbonate resins formed from a dihydroxybenzophenone, a first linker moiety, a diol chain extender, and an end-capping agent. The resulting additives can be crosslinked with other polymers upon exposure to UV radiation.
