本文综述了通过烯烃复分解反应 (ROMP) 催化应变环烯烃开环聚合的明确过渡金属化合物的发展。几种钛环丁烷和钽环丁烷化合物以及钨卡宾和钼卡宾通过“活性”机制聚合降冰片烯和降冰片烯衍生物，从而产生具有窄分子量分布的可控分子量的聚合物。其中一些系统已成功应用于嵌段和接枝共聚物的合成。对钌基催化剂的研究促进了水溶液中烯烃复分解聚合的发展。
The present article reviews the development of well-defined transition metal compounds which catalyze the ring-opening polymerization of strained cyclic olefins by the olefin metathesis reaction (ROMP). Several titana- and tantalacyclobutane compounds and tungsten- and molybdenum carbenes polymerize norbornene and norbornene derivatives by a “living” mechanisms, thus producing polymers of controlled molecular weights with narrow molecular weight distributions. Some of these systems have been successfully applied to the synthesis of block and graft copolymers. Studies on Ru-based catalysts resulted in the development of olefin metathesis polymerizations in aqueous solutions.
