Synthesis, structure and polymerization behavior of tri- and dichloroaminopyridinato complexes of titanium

Three 2-phenylaminopyridine (Ap) complexes of types ApTiCl3 and Ap2TiCl2 were characterized with X-ray diffraction. The complexes were studied as polymerization catalysts using MAO as cocatalyst. In ethylene polymerization, the catalysts showed moderate activities between 65 and 285 kg PE mol−1 Ti−1 h−1 and the molecular weight distributions were between 2.5 and 4.2, and the molar masses were between 135 000 and 804 000 kg/mol.
