Enhancement of Ethylene and Ethylene/1-Hexene (Co)polymerization Activities by Titanium(IV) and Zirconium(IV) Complexes Bearing Constrained Hydroxyindanone-Imine Ligands
Abstract:A new series of catalysts for ethylene and ethylene/1-hexene
(co)polymerizations
bearing constrained hydroxyindanone-imine ligands was developed for
titanium(IV) and zirconium(IV) metals with variations of steric and
electronic contributions on the ligands. X-ray crystal structures
revealed significantly higher open space for the constrained titanium
and zirconium complexes, compared to the conventional FI counterparts.
Upon activation with MAO, significantly higher ethylene polymerization
activities (up to 37… Show more
