Method for preparing transition metal complexes, Transition metal complexes prepared using the mathod, Catalysts composition containing the complexes

摘要

The present invention amido group is introduced mono-cyclopenta dienyl ligand is coordinated with your new transition metal compound, to a synthesis method thereof, and an olefin polymerization using the same. ; method of the transition metal compounds according to the invention by using a compound containing a protecting group includes a step to block the side reaction of the nitrogen atom it is possible to make the transition metal compound in a more simple and high yield because. ; In addition, the transition metal compounds according to the invention are also metal sites by amino group attached to the phenylene ring-shaped bridge is maintained around a very stable, robust 5 gakring structure thus structured as the access of the monomer is very easy. ; copolymer between a catalyst composition comprising the transition metal compound and an ethylene monomer large steric hindrance In addition to the high molecular weight linear low density polyolefin, yet when applied to, the amount of polymer while a density of 0.910g / cc less than the second production of the low-density polyolefin copolymers are available. In addition, the reactivity is very high.
