摘要

Two new FI complexes, bis[N-(3-allylsalicylidene)-pentafluoroanilinato] titanium(IV) dichloride (AFI) and bis[N-(3-propylsalicylidene)- pentafluoroanilinato]titanium(IV) dichloride (PFI) were designed and synthesized as catalysts for living polymerization of ethylene. The two complexes were characterized by elemental analysis, spectroscopy and X-ray single diffraction. The catalysts were evaluated in ethylene polymerization under atmospheric pressure. It was found that both catalysts exhibited high activity and good livingness. The effects of temperature and dMAO/Ti molar ratio on the polymerization behavior of AFI were studied in detail. Elevating temperature increased self-immobilization of the AFI catalyst, which broadened the polymer molecular weight distribution.
