间规聚苯乙烯(syndiotactic polystyrene
SPS)是通过过渡金属配位催化苯乙烯单体聚合制备的新型工程塑料,具有独特的物理化学性质,广泛应用于多种工程技术领域。单茂钛和稀土金属络合物在SPS制备和生产中发挥主要作用。本文对单茂钛及单茂稀土金属络合物的取代基结构、活性物种阳离子金属的种类以及助催化剂等因素对苯乙烯配位聚合立体选择性、聚合活性等的影响进行了简单的梳理总结。
Syndiotactic polystyrene (SPS) is a specialty engineering plastic prepared by transition metal coordinating polymerization of styrene monomer which has excellent physical and chemical properties
and SPS are widely used in various engineering and technical fields. Mono-cyclopentadienyl Ti and rare-earth metal complexes are major driving forces in the preparation and production of SPS. This article provides a brief survey of the effects of cyclopentadienyl substituent structures
types of active metals
and co-catalysts on the stereoselectivity and polymerization activity of styrene coordination polymerization.
