ABSTRACT:
A process is provided to produce polyolefins having a multimodal molecular weight distribution at the molecular level by contacting at least one mono-1-olefin in a polymerization zone, under polymerization conditions, with dual site supported chromium polymerization catalyst systems. Such a polymerization catalyst system comprises an inorganic oxide supported chromium oxide catalyst system and a chromocene compound, wherein the supported catalyst system and chromocene compound are contacted in a polymerization reactor. The resultant, recovered polymer has at least a bimodal, or broad, molecular weight distribution.
