Abstract
Novel catalyst systems which comprise at least two diimine nickel complexes can be used with a co-catalyst such as methylaluminoxane in polymerization processes to produce polymers having multimodal molecular weight distributions. Also disclosed are the novel polymers obtained by the use of such catalyst systems.
