摘要：
The catalytic activity of bis(isopropoxo)titanium(4+) complexes containing 1,2-diolate ligands activated with aluminum alkyl chlorides and dibutyl magnesium in the copolymerization of ethylene and hexene-1 has been studied. The effect of the precatalyst structure and the organoaluminum activator composition on the catalytic activity, the incorporation of hexene-1, and the copolymer microstructure has been studied. The synthesized copolymers have been characterized by DSC, GPC, and(13)C NMR. The complexes containing perfluorophenyl substituents exhibit the highest activity in this set and provide the highest degree of incorporation of the comonomer. The replacement of Et2AlCl with Et(3)Al(2)Cl(2)leads to a significant decrease in both productivity and the degree of incorporation of hexene-1 into the copolymer. The mechanical properties of the resulting copolymers have been studied.
