摘　　要：对聚乳酸的新聚合方法———固相聚合进行了研究 ,探讨了聚合温度、聚合时间、氮气流量、催化剂等对聚乳酸粘均相对分子质量的影响 ;验证了固相聚合方法的有效性。A new route, e.g. direct melting polycondensation/solid state polymerization, to obtain poly(L-lactic acid) in relatively short time is explored. In this process, effects of various polymerization conditions, i.e., polymerization time, temperature, N 2 flowing rate, and catalyst usage etc on the molecular weight of poly(L-lactic acid) are discussed. The experimental results show the efficiency of this new process.
