Abstract

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 ¹³C 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 Et₃Al₂Cl₂ 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.
