Titanium(4+) Complexes with Tetraaryldioxolane Ligands as the Catalysts for the Synthesis of Ultra-High-Molecular-Weight Polyethylene

Titanium(4+) complexes with tetraaryldioxolane-dimethanol (TADDOL) ligands were obtained. Their catalytic activity in the ethylene polymerization was evaluated. It was shown that, in the presence of Al activators, the resulting compounds catalyze the ethylene polymerization highly efficiently (up to 3400 kg PE·mol(Ti)–1·h–1·atm–1), resulting in the formation of ultra-high-molecular-weight polyethylene (UHMWPE) with a molecular weight of up to 4.50 106 Da.
