Abstract��
OBJECTIVE To study the feasible synthesis method of poly-sebacic anhydride.METHODS Poly-sebacic anhydride was prepared via melt polycondensation using the prepolymer which was synthesized with sehacic acid and acetic anhydride. High molecular polyan-hydride can be synthesized under the optimal polycondensation condition. RESULTS Polymer of average molecular about 40 000 was synthesized. CONCLUSION Through the screening of polycondensation condition, poly-sebacic anhydride of high molecular weight was practical.
