窄分子量分布聚己内酯多元醇的合成与表征

Synthesis and Characterization of Polycaprolactone with Narrow Molecular Weight Distribution

通过对合成条件的优化,合成了一系列具有不同分子量的聚己内酯多元醇,并且用FT-IR、1H NMR以及GPC对产物进行了表征。结果表明,通过控制合成工艺,能够将反应产物的分子量分散性系数控制在1.4以下,获得窄分子量分布的聚己内酯多元醇产品。

A series of polycaprolactone with various molecular weight were synthesized. These compounds were fully characterized by FTIR spectroscopy, H NMR and GPC. The results showed that PCL with narrow molecular weight distribution under 1.4 can be get by optimize the reaction parameters.
