    <dcterms:abstract xml:lang="eng">A series of partially novel, (κ2-N,O) Ni(II) methyl complexes coordinated by pyridine or N,N,N′,N′-tetramethylethylenediamine (tmeda), based on different κ2-N,O-chelating salicylaldimines, 2,6-diisopropylanilinotropone, and a ketoenamine, were studied as precatalysts for olefin polymerization in dense carbon dioxide. Bis(trifluoromethyl)phenyl substituents promote solubility in the CO2 reaction medium, as quantified by solubility studies of the free N,OH ligands over a range of CO2 densities (ρ = 0.2−0.9 g mL−1) at 25 and 50 °C and thus enhance catalyst activities. By appropriate choice of the catalyst precursor and polymerization reaction conditions (CO2 density, ethylene concentration, and temperature), strictly linear polyethylene with high molecular weight is obtained (</dcterms:abstract>
