摘要： 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 R 1 , R 2 , R 4 , and R 5 , and a second cyclopentadienyl ring with carbon atoms directly connected with R 10 , R 11 , R 12 , and R 13 , 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.
