IB Catalysts: New Titanium Complexes Having Two Indolide-lmine Chelate Lagands for Ethylene Polymerization

摘要

The development of well-defined group-4 metallocene-complex-catalysts has made a dramatic impact on the polyolefin industry to commercialize high performance polyolefins such as linear low-density polyethylene, isotactic and syndiotactic polypropylenes. Therefore studies on well-defined transition metal complexes have been actively pursued in both academic and industrial research groups, aiming at developing new olefin polymerization catalysts [1-2].
