Catalyst system |
abstract |
The invention relates to a catalyst system containing metallocene, a cocatalyst which contains an organoboron aluminum compound, and optional additional organometallic compounds. The catalyst system can be advantageously used for the polymerization of olefins, whereby the use of aluminoxanes such as methyl aluminoxane (MAO) which normally must be used in high surplus can be abandoned, and nevertheless a high catalyst activity and a good polymer morphology are achieved. |
