摘　　要：在非均相体系中,以含噻二唑环的新型阴离子型聚合引发剂,引发氧化乙烯开环聚合,再分别用甲醇和甲基丙烯酰氯封端,得相应的PEO聚合产物.用IR,NMR,UV对产物进行了表征,用VPO和GPC测定了聚合大单体的分子量及分子量分布.In heterogeneous system, the new kind of polyethylene oxide was synthesized using a new initiator containing thiadiazole, the reactions of polymerization were stoped by adding methanol and MAC. The new kind of PEO(macromonomers)which contains two functional groupes were characterized with IR, ~1H-NMR, UV. The molecular weights of PEO and its distributions were determined with VPO and GPC.
