Abstract
Abstract A series of titanium (IV) complexes 3a-f stabilized by 1,2-diolate ligands 2 a-e have been synthesized. Structures of complexes 3d and 3e have been determined by X-ray diffraction. Titanium atoms in these complexes have a distorted square-pyramidal environment. All resulting complexes are highly active in ethylene polymerization in the presence of {3Et 2 AlCl + MgBu 2 } or {1.5Et 3 Al 2 Cl 3  + MgBu 2 } binary co-catalysts. In the latter case, higher molecular weights of UHMWPE samples (up to 7.7 10 6 ) are achieved. Obtained polymers are suitable for the modern processing methods – the solvent-free solid state formation of super high-strength (over 2.0...
