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.
