水相配位催化烯烃聚合的新进展
Advances of Olefin Polymerization in Aqueous Solutions
【摘要】 水相催化研究已经成为近年来化学反应研究的热点课题。烯烃聚合领域中水相自由基乳液聚合和悬浮聚合等方法早已工业化 ,而前过渡金属烯烃聚合催化剂对水气敏感 ,水相烯烃配位聚合发展缓慢。低亲氧性、高活性的后过渡金属烯烃聚合催化剂的出现使水相催化成为可能。本文综述了后过渡金属催化剂水相催化烯烃配位聚合的一些新进展 ,内容包括乙烯、α-烯烃、环烯烃、二烯烃的聚合反应和环烯烃的开环聚合反应以及 CO/烯烃的共聚反应等方面。
【Abstract】 It is a challenge to proceed catalytic system in aqueous medium on the base of environmental consideration. Although the first aqueous emulsion and suspension polymerization were industrialized long time ago, the polymerization promoted with Ziegler |Natta and Metallocene catalysts has difficulty in aqueous solution due to their high sensitivities to moisture. Recently the great progress of olefin polymerization has been made with the advent of low oxophilic late |transition metal catalysts. Herein the latest developments of olefin aqueous polymerization which are mainly promoted by late |transition metal catalysts are reviewed including ethylene, α |olefins, cyclo |olefins and dienes polymerization, along with ROMP of cyclo |olefins and CO/olefins copolymerization.
