Abstract Summary: Vinyl sugar ester, 1′‐ O ‐vinyladipoyl‐sucrose, was synthesized using sucrose and DVA (divinyl adipate) in organic medium (dimethylformamide), catalyzed by protease from Bacillus subtilis . Several reaction conditions were examined by means of qualitative analysis (TLC). The monomer obtained has undergone chemical polymerization with potassium persulfate and hydrogen peroxide to produce an amphiphilic polymer having sugar branches. The monomer was characterized by 13 C‐NMR and FTIR spectra. The IR analysis confirmed the synthesis of the poly (1′‐ O ‐vinyladipoyl‐sucrose).
