Abstract
The present disclosure relates to metallocene catalysts for use in polymerization processes. Such catalysis may be used to generate long chain polymers with low long chain branching and high molecular weights. Additionally, the size of the polymers produced can be controlled by modifying the ratio of MAO or other activator to metallocene catalyst.
