摘要： This invention relates generally to supported metallocene catalyst systems and to methods for their production and use. Specifically, this invention relates to supported metallocene catalyst systems having improved metallocene loading and optionally reduced support particle size. These catalyst systems are particularly useful for the polymerization of ethylene polymers.
