摘要
用于烯烃聚合的后过渡金属催化剂的设计开发在聚烯烃研究领域受到了极大的关注。本文综述了几类后过渡金属催化剂体系的研究进展,包括α-二亚胺型、水杨醛亚胺型、膦磺酸型、膦-氧化膦型和膦酚型催化剂,并简述了通过改变催化剂结构调节催化性能的方法,总结了这些催化剂催化乙烯均聚及乙烯与其他单体共聚时对催化活性、支化度和相对分子质量等方面的影响规律。采用先进后过渡金属催化剂能够合成其他聚合手段无法获得的新型聚合物。
The design strategies of late transition metal catalysts for olefin polymerization had received substantial attention in the field of polyolefin research.The development of late transition metal complexes was reviewed,such asα-diimine,salicylaldimine,phosphine-sulfonate,bisphospnine monoxide and phosphino-phenolate,several methods of changing the catalyst structure to adjust the catalytic performance were briefly described.The effects of these catalysts on the activity,branching degree,and relative molecular mass of ethylene homopolymerization and copolymerization with polar monomers were summarized in detail.Novel polymers that cannot be obtained by other polymerization methods could be prepared by using advanced late transition metal catalysts.
