Abstract:
1. A method, comprising: forming an initial emulsion by combining with agitation i) a first mixture comprising a first monomer and a water immiscible organic solvent with ii) a second mixture comprising water and a surfactant, wherein the first monomer comprises two or more pentafluorophenyl carbonate (PFPC) groups having the structure combining with agitation the initial emulsion and a third mixture, the third mixture comprising water and a second monomer, thereby forming a second emulsion that includes the first monomer and the second monomer, wherein the second monomer comprises two or more nucleophilic amine groups, and each of the two or more nucleophilic amine groups is capable of reacting with a respective PFPC group of the first monomer to form a respective carbamate group; and allowing the first monomer and the second monomer of the second emulsion to react by interfacial polymerization, thereby forming a polyurethane, wherein the polyurethane has a number average molecular weight (Mn) of about 30000 to about 80000.
