Process for the polymerization of olefins |
(57) Mixtures of different polyolefins or branched polyolefins may be made by direct,
preferably simultaneous, polymerization of one or more polymerizable olefins using
two or more transition metal containing active polymerization catalyst systems, one
of which contains preferably late transition metals complexed to selected ligands.
The polyolefin products may have polymers that vary in molecular weight, molecular
weight distribution, crystallinity, or other factors, and are useful as molding resins
and for films.
