Abstract:
A process for polymerizing an olefin comprising contacting said olefin under suitable polymerization conditions in the absense of another olefin with a catalyst system comprising a metallocene and a suitable cocatalyst, wherein the metallocene is selected from metallocenes of the formula Râ€³(FlRn)2MQk wherein Fl is a fluorenyl radical, each R is the same or different and is an organo radical having 1 to 20 carbon atoms, Râ€³ is a structural bridge linking (FlRn) and (CpRm), M is a metal selected from the group consisting of group 4 and 5 metals of the Periodic Table, each Q is the same or different and is selected from the group consisting of hydrocarbyl and hydrocarbyloxy radicals having 1 to 20 carbon atoms and halogen, k is a number sufficient to fill out the remaining valences of M, n is an integer in the range of 0 to 7, m is an integer in the range of 0 to 7, wherein the olefin that is polymerized is selected from alpha olefins having 3 to 10 carbon atoms.
