| Abstract: | Polyether(primarily homopolymers and copolymers of ethylene oxide and propylene oxide) which has the properties of excellent surface activity,flexibility of hydrophile_lipophile balance(HLB) and low toxicity has been widely used in surfactant and polyurethane industries.The progress in the catalytic ring-opening polymerization of ethylene oxide and propylene oxide is reviewed in this paper.The different catalytic mechanisms of cationic catalysts,anionic catalysts and coordination catalysts are discussed respectively.The application of coordination catalysts in the catalytic ring-opening polymerization is intensively introduced and the further research trends are pointed out. |
