低碳烯烃聚合催化剂的研究新进展

介绍了近来来烯烃聚合催化剂研究所取得的一些新进展,它们包括Ziegler-Natta催化剂、茂金属催化剂、非茂金属催剂、某些亚胺类后过渡金属(Ni、Pd、Fe、Co)配合物催化剂以及其它用于烯烃聚合的新型催化剂等。对世界一些主要石化公司生产PE及PP所采用的催化剂近况也作了简单表述。目前世界茂金属催化剂发展迅速,对于烯烃聚合新品种的开发具有潜在而广阔的工业应用前景和重要价值。

Research Progress of Catalyst for Polymerization of Low Carbon Number Olefin

The catalysts for olefin polymerization were reviewed in the paper, including Z -N catalyats, MAO catalysts ,no-MAO catalys etc. Polymers under no-MAO cayalysts have well process poperties and good physica poperties, no-MAO catalysts will push the development of polyolefin . Salicylaldimine transition metal complexes , for olefin polymerization were introduced also. These catalysts were easily synthesized and had high catalytic activity , lower cost, and worth in industrial application. Metallocene catalyst...
