Ethylene/1-hexene copolymerization was carried out with a new Ti (IV) complexes stabilized by fluorinated 2-hydroxymethylphenol derivatives and activated by MAO-free binary cocatalysts—{alkyl aluminum chloride + Bu2Mg}. Structures and properties of the obtained copolymers were measured by DSC, GPC and 13C NMR. The effects of the ligand structure and the nature of organoaluminum activator on the polymer yield, comonomer incorporation, polymer composition, molecular weight, polydispersity index and stress–strain behavior have been investigated. The results indicated that the complex with adamantyl substituent was the most active in this series. The obtained copolymer exhibited the highest 1-hexene incorporation content of 18.9 mol%

乙烯和1-己烯与含氟2-羟甲基苯酚衍生物负载的Ti（IV）配合物的无MAO共聚

乙烯/1-己烯共聚是使用由氟化2-羟甲基苯酚衍生物稳定并由不含MAO的二元助催化剂{烷基氯化铝+Bu2Mg}活化的新型Ti（IV）配合物进行的。所得共聚物的结构和性能通过DSC、GPC和13C NMR测量。已经研究了配体结构和有机铝活化剂的性质对聚合物产率、共聚单体掺入、聚合物组成、分子量、多分散指数和应力应变行为的影响。结果表明，具有金刚烷基取代基的配合物在该系列中活性最高。所得共聚物的 1-己烯掺入量最高，为 18.9 mol%
