摘要：
A mixed metallocene catalyst system can comprise at least one metallocene catalyst compound comprising a structure represented by formula (A) below and optionally at least one other metallocene catalyst compound having a structure represented by formula (B) below: A mixed metallocene catalyst system can additionally include a non-coordinating anion type activator comprising a supported alumoxane or aluminum alkyl, and optionally a scavenger. A process for making a polymeric product can comprise: contacting a C 2 -C 22 alpha-olefin feed with the catalyst system to obtain a polymerization reaction mixture; and obtaining a polymer product from the polymerization reaction mixture. A polymer product can be made by the process.
