Abstract

The review summarizes the results obtained by the authors in a study of the polymerization of 1‑hexene on a supported titanium–magnesium catalyst. The effects of the composition of a complex titanium–magnesium catalytic system, the composition of a reaction medium, and the conditions of polymerization on the activity of the catalyst and the molecular weight, molecular-weight distribution, and isotacticity of the resulting polyhexene were considered. The main factors (the composition of a catalytic system and the polymerization conditions) that allow one to control the catalyst activity and the molecular structure of polyhexene over wide ranges were determined. Specific features of the polymerization of 1-hexene in comparison with the polymerization of ethylene and propylene on titanium–magnesium catalysts are discussed.

1-己烯在高活性钛-镁催化剂上的聚合

摘要

该综述总结了作者在负载型钛-镁催化剂上1-己烯聚合研究中获得的结果。考虑了复杂的钛-镁催化体系的组成，反应介质的组成以及聚合条件对催化剂活性以及所得多己烯的分子量，分子量分布和全同立构规整度的影响。确定了可以在较大范围内控制催化剂活性和聚己烯分子结构的主要因素（催化体系的组成和聚合条件）。讨论了1-己烯聚合与钛-镁催化剂上乙烯和丙烯聚合的特定特征。
