摘要
本文介绍了在乙酸酐—高氯酸催化下四氢呋喃开环聚合制备端羟基聚四氢呋喃反应的研究。探讨了催化剂组成和用量对聚合物分子量的影响。并用ＦＴ—ＩＲ、’ＨＮＭＲ对聚合物的结构进行了表征。
Hydroxy terminated polytetermethyleneoxide was prepereted by using acetic anhydride andPerchloric acid as catalyst,The effects of the amounts of the Catalyst on the molecular weigh werestudied. The Products were measured by means of FT-IR and NMR. The results show that themolecular weigh of the polymer was increasing with the increase of the amount of perchloric acidand decreasing with the increase of acetic anhydride in the catalyst
