Abstract
A boron-containing zwitterionic neutral transition metal compound which can advantageously be used for the polymerization of olefins is described. Here, the use of aluminoxanes, such as methylaluminoxane (MAO), as a cocatalyst can be dispensed with and a high catalyst activity and a good polymer morphology can nevertheless be achieved.
