Metallocene and constrained geometry catalyst systems using aggregated metal oxide / clay support-activators and methods for their preparation |
| abstract |
(57) [Summary]nThe present invention relates to at least one metallocene or transition metal compound that is a constrained geometry catalyst precursor [eg, di- (n-butylcyclopentadienyl) zirconium dichloride] and at least one support-activator (eg, spray). A coordination catalyst system comprising a controlled amount of a dried silica / clay agglomerate) and optionally at least one organometallic compound, such as triisobutylaluminum, and a process for its preparation. The resulting catalyst systems show improved activity in the polymerization of olefins and result in polymers with very good morphology. |
