摘要：
The catalytic activity of the systems based on titanium(iv) alkoxides (Ti(OPri)(4), Ti(OPri)(2)(OCH(CF3)(2))(2), and Ti(OCH(CF3)(2))(4)) and mixtures of alkylaluminum chlorides (Et2AlCl or Et3Al2Cl3) with dibutylmagnesium in ethylene polymerization and ethylene copolymerization with propylene and 5-ethylidene-2-norbornene was studied. Ultrahigh-molecular-weight polyethylene with the molecular weight reaching 4.9 center dot 10(6) Da was found to be formed in the homopolymerization reaction, whereas copolymerization gives ter-copolymers containing propylene (up to 35 mol.%) and 5-ethylidene-2-norbornene (4.3 mol.%) units.
