NOVEL TRANSITION METAL COMPOUND, TRANSITION METAL CATALYST
COMPOSITION CONTAINING THE SAME, AND METHOD FOR PRODUCING
COPOLYMER OF ETHYLENE AND a-OLEFIN USING THE SAME
摘要:
The present disclosure relates to a novel transition metal compound, a transition metal catalyst composition having high catalytic activity for producing a copolymer of ethylene and α-olefin containing the same, a method for producing a copolymer of ethylene and α-olefin using the same, and a copolymer of ethylene and α-olefin produced using the same.

Seventeen new catalyst. precursors for the syndiospecific polymerization of propylene are presented. The new metallocene complexes are substituted in the positions 2 and 7 of the fluorenlidene fragment by MeO-, halogen-, alkyl- and aryl groups. The focus is directed on effective new synthetic routes to substituted fluorenes and the preparation of Be catalyst precursors. In addition first polymerization results are reported.
