ABSTRACT:
A polymerization catalyst system, containing a specified ratio of two iron complexes of a bisimine of 2,6-diacylpyridine or a bisimine of a 2,6-pyridinedicarboxaldehyde which produce polyolefins of differing molecular weights, is useful for producing polyolefins, especially polyethylenes, which are particularly useful for blow molding.
