Abstract

The invention relates to a catalyst composition containing at least two different polymerization catalysts of which a) at least one is a polymerization catalyst based on an early transition metal constituent and b) at least one is a polymerization catalyst based on a late transition metal constituent.

Claims

exact text as granted — not AI-modified
1 . Catalyst composition containing at least two different polymerization catalysts, of which a) at least one is a polymerization catalyst on the basis of an early transition metal component and b) at least one is a polymerization catalyst on the basis of a late transition metal component.  
     
     
         2 . Catalyst composition in accordance with  claim 1 , wherein the early transition metal component is a Ziegler catalyst component and/or a metallocene catalyst component.  
     
     
         3 . Catalyst component in accordance with  claim 1  or  2 , wherein each of the transition metal components has a productivity that is greater than 2800 kg polymer/(mol transition metal×hr).  
     
     
         4 . Catalyst composition in accordance with one or more of the  claims 1  to  3 , additionally containing one or several activators.  
     
     
         5 . Catalyst composition in accordance with one or more of the  claims 1  to  4 , simultaneously containing one or more supports.  
     
     
         6 . Process for polymerization of olefins in the presence of a catalyst composition in accordance with one or more of the  claims 1  to  5 .  
     
     
         7 . Process in accordance with  claim 6 , wherein ethylene is polymerized.  
     
     
         8 . Polyolefin that can be produced in accordance with the process of  claim 6  or  7 .  
     
     
         9 . Use of a catalyst composition in accordance with one or more of the  claims 1  to  5  for olefin polymerization.
