Bridged metallocene catalysts with a pendant group 13 element, catalyst systems containing same, processes for making a polymer product using same, and products made from same
Abstract:
A metallocene catalyst compound can comprise a structure represented by formula (F-MC) below comprising a first cyclopentadienyl ring with carbon atoms directly connected with R1, R2, R4, and R5, and a second cyclopentadienyl ring with carbon atoms directly connected with R10, R11, R12, and R13, and a bridging group (BG) directly connecting the first and second cyclopentadienyl rings A catalyst system can include the metallocene compound, 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 C2-C22 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 to exhibit at least an Mn from 7000 g/mol to 70000 g/mol and a PDI from 4.1 to 9.0.
