摘要

石化工业最重要的产品是聚烯烃，其中大部分与聚乙烯相关，α-烯烃不仅是重要的共聚单体，也是精细化工的基本原料，乙烯工业发展程度代表了一个国家石化技术的水平。后过渡金属催化剂作为新型催化体系，能够高效催化乙烯齐聚和聚合，并且乙烯聚合可制备新型聚乙烯树脂。通过对配体的修饰，提高后过渡金属配合物催化活性，增加催化体系的热稳定性，仍然是当前催化剂设计的重要课题；实现对所得聚乙烯微观结构的控制，提高聚烯烃宏观性质是产业化的重要基础。本文基于配合物催化剂配体骨架设计为基础，集中讨论了铁、钴和镍配合物用于乙烯聚合和齐聚的性质比较；特别是集中展示了我们近期研究工作，综述了后过渡金属催化剂的新进展。

Abstract

Polyolefin is the most important product of petrochemical industry

and majorly related to polyethylene

meanwhile α-olefins are not only co-monomer in co-polymerization but also basic substance for fine-chemical industry. Therefore the national ethylene industry represents the technical development of petrochemical industry. Regarding the newly developing process in ethylene industry

late-transition metal precatalysts achieve highly activities in oligomerization and polymerization

in which the resultant polyethylenes potentially become new plastic materials of polyethylenes. It is still a hot topic of developing new precatalysts through modifying coordination ligands to enhance the activities and thermal-stabilities of late-transtion metal complexes ; the finely controlled microstructures of resultant polyethylenes resulted the better properties and provided essentials toward industrial process. Relied on variations of ligands' classifications

the complex precatalysts of iron

cobalt and nickel have been compared in their performances in ethylene oligomerization and polymerization. The new progress has been reviewed

specially focusing on our researches.
