Abstract:
1. A process for producing a macro-photoinitiator via enzymatic polymerization, the process comprising: providing a reaction solution comprised of at least one monomer and at least one reactive photoinitiator having at least one reactive moiety reactive with the at least one monomer, contacting the reaction solution with at least one enzymatic catalyst, and heating to enzymatically polymerize the at least one monomer and form a polymeric product solution comprised of a macro-photoinitiator, wherein the macro-photoinitiator has the at least one reactive moiety of the at least one photoinitiator covalently bound to a polymer moiety formed from the at least one monomer, wherein the photoinitiator of the macro-photoinitiator includes an OH group, and wherein the at least one monomer is selected from the group consisting of oxacycloheptadec-10-en-2-one, pentadecalactone, pentadecenlactone, hexadecenlactone and caprolactone, cyclic diester lactide, butyrolactone, propyl malolactone, propiolactone, 1,4-dioxan-2-one, valerolactone, and mixtures thereof.
