摘要
环氧乙烷和环氧丙烷由于具有较高的环张力,因而容易发生开环聚合。本文综述了环氧乙烷和环氧丙烷开环聚合反应的动力学研究进展,考察了环氧乙烷和环氧丙烷开环聚合反应的机理,分别讨论了各类催化剂体系中环氧乙烷和环氧丙烷开环聚合的动力学常数、两者的竞聚率及开环聚合产物的分子量分布,并指出了开环聚合反应动力学研究对于环氧乙烷和环氧丙烷的开环聚合研究及工业应用的重要性。
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
