The advances in the late transition metal catalysts for olefin polymerization

This paper reviewed the latest progresses of a series of late transition metal (Ni, Pd, Fe and Co) catalyst systems incorporating a - diimine ligands used in olefin polymerization, cycloolefin addition polymerization, ethylene oligomerization and copolymerization of olefins with polar monomers. The effects of different late transition metal ion, a - diimine backbone and the ligand on it, different polymerization conditions (temperature and pressure) on the catalyst's polymerization activity, branching degree, molecular weight and its distribution of the polymer and the properties of the polymer products were elucidated systematically. The preparation methods and the new characters of the catalysts of this kind were also described briefly.
