Three 2-phenylaminopyridine (Ap) complexes of types ApTiCl(3) and Ap(2)TiCl(2) 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.
