    摘要: An elastomeric nanocomposite is produced from an isobutylene-based polymer and a layered nanofiller. The process of preparing the nanocomposite includes the steps of a) polymerizing isobutylene monomers and multiolefin monomers to produce an isobutylene-based polymer; b) completing at least one mass transfer dependent stage in the process wherein, after completion of the stage and prior to any recovery of the polymer, the polymer is dissolved in a solvent to create a polymer cement; c) contacting the layered nanofiller and the polymer solvent to obtain the nanocomposite; and d) recovering the nanocomposite. The layered nanofiller may be in a slurry prior to contacting with the polymer cement.

    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.

    摘要: An elastomeric nanocomposite contains: (a) at least one elastomer comprising units derived from isoolefins having from 4 to 7 carbon atoms; (b) at least 10 phr of a carbon black; and (c) at least 1 phr of a nanoclay; wherein when the nanocomposite is used in an article, the article has a gas permeation coefficient of 80.0 cc*mm/[m2-day] at 40° C. The carbon black may be graphitized to reduce interactions between the carbon black and the nanoclays. The elastomeric nanocomposite may, with or without the use of the graphitized carbon black, may calendared or extruded in such a manner as to orient the nanoclay platelets within the composition such that the oriented nanoclay elastomer nanocomposite has an orientation parameter of greater than 0.15.
