Olefin copolymer with a transition metal initiator, and polar comonomer carried ketone diimine ligands for a single polymerization of olefins

摘要

Metal ligand compound initiator to produce organometallic complexes enables the polymerization of olefins to higher molecular polymer. In addition, these initiators may also allow copolymerization of olefins with functionalized monomers. These organometallic complexes include a transition metal after with neutral chelating ligands comprising Lewis basic functional group, wherein the Lewis basic groups of delocalized electrons to extend the functionality of metal It is bound to the conduit. The feature of this structural, high active complex is obtained, which produces a high molecular weight polymer with a unique microstructure. Under certain conditions, the organometallic complex provides a living polymerization of monomers and comonomers. .FIELD 8
