Abstract

The polymerization of olefins is carried out in the presence of catalysts comprising at least one complex of a transition metal with a tridentate macrocyclic ligand which additionally bears at least one functional substituent and, if desired, one or more activator compounds. A catalyst system comprising at least one transition metal complex as set forth above and at least one activator compound is also provided.
