The (arylamino)methylene phenolate titanium (IV) complexes are thermally stable and active to promote ethylene polymerization and copolymerization with 1-alkenes at a high temperature (up to 150 °C). 1-Octene and 1-octadencene are suitable comonomers. The highest activity is 1.89 × 106 g/mol·Ti·h·atm. The introduction of the pendant PPh2 group is important to the catalytic behaviors of the complexes.
