摘要
目的研究聚癸二酸酐适宜的合成方法。方法以癸二酸和乙酸酐为起始原料,合成预聚物,经熔融聚合得到产物,采用正交设计法优化聚合条件得到较高相对分子质量的聚酐。结果在最优化条件下聚合,可以得到平均相对分子质量约40 000的聚合物。结论通过对聚合条件的筛选,合成了相对分子质量较高的聚酐。
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.
