Abstract
Different interfacial processes for producing photoactive additives are disclosed. Generally, the photoactive additives are formed from a photoactive moiety, a first linker moiety, and a diol chain extender. The resulting additives can be crosslinked with other polymers upon exposure to UV radiation.
