3-甲基吗啉-2,5-二酮与ε-己内酯共聚物的制备与表征

Copolymerization and Characterization of 3-Methyl-Morpholine-2,5-Dione and ε-Caprolactone

以辛酸亚锡为催化剂,合成了3-甲基吗啉-2,5-二酮(MMD)与ε-已内酯(ε-CL)的共聚物,并用FT-IR、1HNMR、DSC、粘度测定等分析方法对共聚物进行了表征.结果表明,MMD能很好地与ε-己内酯进行共聚,且共聚物的性能可以根据投料比例的不同在很大范围内进行调节.

A series of copolymers of ε-caprolactone with 3-methyl-morpholine-2, 5-dione are synthesized by using stannous octoate as catalyst. The results show that this means can gain copolymer of ε-caprolactone and MMD. Furthermore, the properties of the copolymer can be adjusted by changing the ratio in feed.
