In Ziegler catalysts based on a metallocene as the transition-metal component and on an aluminoxane as activator, preactivation of the metallocene by means of the aluminoxane results in a significant increase in the activity of the catalyst system. Furthermore, use of a catalyst system of this type gives 1-olefin polymers which have high isotacticity, compact spherical particles, a very narrow particle size distribution and high bulk density.

Title
