Reaction Steps

Butyl acrylate (24.4 g, 0.19 mol), and N-(3-(methacrylamido) propyl)-3,4,5-triacetoxybenzamide (IV) (4.20 g, 0.010 mol) were combined with 110 mL ethyl acetate and azobis(isobutyronitrile)(0.16 g) in a vessel sealed with a septum. The vessel was purged with N2 and heated to 60° C. with agitation for 24 h. Additional AIBN (0.16 g) was added and the mixture was heated for an additional 24 h. Yield 124.7 g solution, 22.6% solids. 1H NMR of an evaporated sample showed no residual monomers and was consistent with the desired copolymer structure. Inherent viscosity in ethyl acetate at 25° C., c=0.238 g/dL; ηinh=0.44. The polymer in ethyl acetate solution was then dispersed in a gelatin solution containing surfactant, followed by removal of the ethyl acetate by evaporation before use.
