    摘要: The disclosure provides for a process and polymerization system to produce isoolefin polymers (72) utilizing polymorphogenates (16, 26) in the catalyst system to control polydispersity (MWD). The disclosure also provides a catalyst system (20) comprising a plurality of active catalyst complex species (34) formed by combination of a Lewis acid (24), an initiator (22) and a polymorphogenate (26), as well as polymers made using the catalyst system or process. The polymorphogenate (16, 26) can promote or mimic the formation of different active catalyst complex species (34) having different polymerization rates, i.e. different rates of propagation, chain transfer, or termination, as observed by different polydispersities resulting from the presence of relatively different proportions of the polymorphogenate.
