摘　　要：以氧化乙烯开环聚合为探针反应,考察了含噻二唑环的新型阴离子聚合引发剂(TDZ-K)的引发活性。反应在非均相中进行,分别用甲醇和甲基丙烯酰氯封端,得含双官能团的氧化乙烯聚合产物,其结构经IR,1H NMR,UV,VPO和GPC表征。加入乙酰丙酮,18-冠-6及PEO作助剂,有助于提高TDZ-K的引发活性。Polyethylene oxide with two functional groups was synthesized using TDZ-K as an anionic initiator. The polymerization in inhomogeneous phase were stoped by methanal and methacrylic chlo- fide（MAC：）, The products were characterized by IR,^1H NMR, UV, VPO and GPC. The activity of TDZ-K was raised inthe ring-opening polymerization using acetyl-acetone, 18-c-6, PEO as the auxil- iary reagent, respectively.
