Ethylene polymerization catalyzed by Titanium(IV) complexes of a triaryloxoamine ligand [TiX{(OArCH2)(3)N}]
Titanium complexes containing a triaryloxoamine ligand [TiX{(O-2,4-R2C6H2-6-CH2)(3)N}] (R = Me, tBu; X = OiPr, O-2,6-iPr(2)C(6)H(3)), exhibited notable catalytic activity for ethylene polymerization in the presence of MAO, especially at temperatures between 100 and 120degreesC. Their activity increased upon the addition of a small amount of AlMe3.
