The kinetic behavior of homogenous iron-based catalysts bearing 2,6-bis (imino) pyridyl ligands for ethylene polymerization

摘要

There is intense interest in the area of late transitionmetal catalysts for the polymerization of olefins. Of particular recent interest is the novel family of catalysts based on iron and cobalt reported by M.Brookhart and V.C.Gibson. Their finding has been regarded as a breakout in the field of polyolefins but the polymerization behavior of these catalysts has not been revealed.
