A metallocene compound for a catalyst system, a process for its use and a process for producing the metal compound |
abstract |
The invention relates to a metallocene compound for a catalyst system and to a process for its use in olefin polymerization and to a process for preparing the metallocene compound. The aim of the inventive solution is to make it possible to produce polyolefins having a higher molecular weight while at the same time having a narrow molecular weight distribution. According to the present invention, this is accomplished by finding a compound of a metallocene having a simple mono- or polycyclic cyclopentadienyl ligand and a heteroatom ligand of an element of group V A, VI A joined to a transition metal atom of group IV B. The catalyst system of the present invention contains a Group IV B transition metal component and an alumoxane component, and is used in the polymerization of olefins to produce a high molecular weight polymer.
