Реферат (описание изобретения):
The present disclosure provides metallocene catalysts for use in polymerization processes. Such catalysts may be used to generate polymers with low branching and high molecular weights. Also, the present disclosure provides methods of bimodal polymerization resulting in a duality of average molecular weight polymers being simultaneously produced. In the system, the size of the polymers produced can be controlled by modifying the type and amount of catalyst activator.
