A new kind of polyesteramide based on 3-morpholinone and ε-caprolactone was synthesized by ring opening polymerization with zinc powder as catalyst. The polymer was characterized by 1 H NMR, GPC and FT-IR. The effect of time, temperature and ratio of m（M）/m（I）, n（M）/n（CL） on the reaction was studied. The results show that the optimal reaction temperature is 120℃; the optimal duration of reaction is 24 h; the optimal ratio of m（M）/m（I） is 50∶1; the optimal ratio of n（M）/n（CL） is 1∶2. Under the optimal condition the polymer whose M n was 13 509 could be obtained while the weight yield was 79%. 聚（3-吗啉酮-ε-己内酯） 3-吗啉酮 ε-己内酯 锌粉 聚酯酰胺 开环聚合 poly（3-morpholinone-ε-caprolactone） 3-morpholinone ε-caprolactone zinc powder polyesteramide ring-opening polymerization O633.1 国家重点基础研究发展规划项目（G1999064703） 2004-02-01 2021-04-01 2
