| Abstract: | Due to the high degree of strain in the small 3-membered ring, the ring-opening polymerization of ethylene oxide and propylene oxide is initiated easily. The progress in the ring-opening polymerization kinetics of ethylene oxide and propylene oxide is reviewed in this paper. The kinetics of the ring-opening polymerization, the reactivity ratios of ethylene oxide-propylene oxide copolymerization and the molar mass distribution of polyether are discussed respectively. The importance of the research in the ring-opening polymerization kinetics is emphasized |
| Keywords: | ethylene oxide propylene oxide ring-opening polymerization kinetics reactivity ratio molar mass distribution |
