摘　　要：以1,3,5-三羟乙基异氰脲酸酯(THEIC)为引发剂、三氟化硼乙醚络合物为催化剂,环氧化合物为环单体,进行了阳离子开环聚合反应的研究。发现THEIC与环氧单体可在非均相体系中平稳地进行阳离子开环聚合反应。在THEIC体系,就链引发而言,环氧氯丙烷的大于环氧丙烷、丁基醚环氧乙烷。调整环单体加料次序就可以获得嵌段共聚醚多元醇。The cationic ring-opening polymerizations of epoxide based monomers were studied using tris （2 hydrooxyethyl） isocyanurate （THEIC） as initiator and trifluoroboron plus ether complex system as catalyst. It was found that the ring opening polymerizations of epoxide based monomers with THEIC can be carried out in a heterogeneous medium smoothly. However, using THEIC initiator, the reaction rate for epichlorohydrin is faster than that of propylene oxide and 2-butoxyxirane, respectively. By simply adjusting the monomer feeding sequence, the block poly（ether glycol） copolymers containing isocyanurate segments can be prepared successfully.
