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.
Claims53
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.
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 dihydroxy compound, tertiary amine catalyst, water, and water-immiscible solvent to form a reaction mixture;
- adding the carbonate precursor to the reaction mixture over a first time period;
- and
- adding the monohydroxybenzophenone to the reaction mixture during the first time period to obtain the photoactive additive.
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 dihydroxy compound, water, and water-immiscible solvent to form a reaction mixture;
- adding the carbonate precursor to the reaction mixture to convert the dihydroxy compound into a chloroformate;
- adding the monohydroxybenzophenone to the reaction mixture and reacting the reaction mixture;
- and
- adding the tertiary amine catalyst to the reaction mixture and reacting the reaction mixture to obtain the photoactive additive.
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:
- pre-reacting the monohydroxybenzophenone with the carbonate precursor in a tubular reactor to convert the monohydroxybenzophenone into a monochloroformate;
- combining the dihydroxy compound, tertiary amine catalyst, water, and water-immiscible solvent in a reaction mixture;
- adding the carbonate precursor to the reaction mixture over a first time period;
- and
- adding the monochloroformate compound to the reaction mixture throughout the first time period to obtain the photoactive additive.
