Appeal No. 1999-2506
Application No. 08/545,254
THE INVENTION
The invention is directed to a process for polymerizing an olefin monomer. The olefin
monomer to be polymerized includes ethylene, an alpha olefin having three or more carbon
atoms or both. The catalyst utilized in the polymerization process comprises a metallocene
compound having an unsubstituted or substituted fluorenyl moiety, a dicyclopentadienyl
moiety and containing a diarylsilanediyl bridging moiety. Additional limitations are disclosed
in the following illustrative claim.
THE CLAIM
Claim 7 is illustrative of appellants’ invention and is reproduced below.
7. A process for producing an olefin polymer, which comprises
polymerizing ethylene or an alpha-olefin of three or more carbons or both at a
polymerization temperature of not lower than 120/C with a catalyst, said
catalyst comprising:
(a) a metallocene compound having an unsubstituted or substituted
fluorenyl group having the formula (I):
