Abstract:
1. A method, comprising: forming a first mixture comprising i) a first cyclic carbonyl monomer comprising a pentafluorophenyl ester and a cyclic carbonyl group, the cyclic carbonyl group selected from the group consisting of cyclic carbonate, cyclic urea, cyclic carbamate, cyclic thiocarbonate, cyclic thiocarbamate, and cyclic dithiocarbonate, ii) a nucleophile selected from the group consisting of an alcohol, amine, and thiol, iii) an optional catalyst, and iv) an optional solvent; and agitating the first mixture at a temperature effective to form a second mixture comprising a second cyclic carbonyl monomer derived from the first cyclic carbonyl monomer without altering the cyclic carbonyl group of the first cyclic carbonyl monomer, wherein the second cyclic carbonyl monomer comprises an amide, an ester and/or a thioester derived from the pentafluorophenyl ester group.
