烯烃聚合催化剂的ESR研究进展

摘要/Abstract

摘要：

很多烯烃聚合催化剂都含有过渡金属离子. 由于很多过渡金属离子存在未成对电子，ESR可以检测这些含有未成对电子的过渡金属离子，所以ESR检测技术可以被用于聚烯烃催化剂的研究. 该文综述了近年来ESR技术在烯烃聚合催化剂表征领域的研究进展，根据不同过渡金属分类讨论，主要涉及了Ti、Ni、V、Cr等几种常见的过渡金属催化剂的ESR研究.

Abstract:

Many polymerization catalysts have different transition-metal centers. In situ- ESR can be used to monitor these transition metal centers having one or more unpaired electrons. Thus the reaction route and mechanisms of polymerization can be investigated by in situ ESR. In this paper, recent research progresses in ESR studies on catalysts for olefin polymerization are reviewed, including common olefin polymerization catalysts based on Ti, Ni, V and Cr.

Key words: electron spin resonance, mechanism, catalyst, olefin polymerization
