摘要
有机金属烯烃配位聚合催化剂具有高催化活性和良好的分子剪裁性,通过调节催化剂的微结构,如配体的取代基、配位原子以及配位中心的电子与立体环境等,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,从而得到各种具有新型功能和立体异构的聚合物。本文综述了金属烯烃聚合催化剂研究进展,并展望该领域的发展趋势。
Organometallic catalysts play an important role in the polymerization of olefins. These catalysts have high catalytic activity with molecular tailoring properties. They are able to tailor the microstructure of the polymer chain by changing functional groups and coordination atoms of ligands, or by alternating electronic and stereoscopic environments of coordination center in catalysts. Molecular design and assembly of catalysts can be achieved at molecular level. New types of polymers with novel structures, morphology, properties and functions can be obtained. Herein, we reviewed the discovery, development, the polymerization characteristics and the most significant recent studies of organometallic catalysts for olefin polymerization.
