INTERFACIAL PROCESSES FOR PREPARING PHOTOACTIVE ADDITIVES

摘要

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.

1. A process for preparing a photoactive additive from a monohydroxybenzophenone, a dihydroxy compound, a carbonate precursor, a tertiary amine catalyst, water, and a water-immiscible organic solvent, comprising:
combining the monohydroxybenzophenone, dihydroxy compound, tertiary amine catalyst, water, and water-immiscible solvent to form a reaction mixture; and adding the carbonate precursor to the reaction mixture to obtain the photoactive additive.
