摘要
由于过渡金属催化剂在烯烃聚合方面具有高活性和良好的分子剪裁性,通过调节催化剂的微结构或温度、压力等聚合环境的变化,可以在分子层次上实现烯烃聚合物的分子设计与组装,实现聚合物物理性质的调控,最近引起了人们的广泛关注。本文介绍了过渡金属催化剂的合成及其负载化,水相烯烃聚合及活性聚合等方面的研究进展。
Transition metal catalysts have high catalystic activity and molecular tailoring properties in the field of olefin polymerization. Design and assembley of olefin polymers can be obtained at molecular level by tailoring the microstructure of these catalysts and controlling the polymerization environment such as temperature or pressure. New polymers with novel properties could be obtained, so these catalysts have been attracted much attention in recent years. In the present review, the recent synthesis and support of these catalysts, as well as aqueous and living polymerization are reported.
