Abstract:
1. A process for producing an isoolefin-diolefin rubber comprising: (a) reacting an isoolefin with a diolefin in a liquid non-aqueous reaction medium in a reaction vessel at a temperature in a range of from −110° C. to −50° C. to produce an isoolefin-diolefin rubber in a slurry; (b) expressing the slurry in a separation zone to separate at least part of the liquid non-aqueous reaction medium from the isoolefin-diolefin rubber; (c) transporting the separated liquid non-aqueous reaction medium off stream; and, (d) transporting residual slurry to a slurry processing zone, wherein the processing zone is a flash tank.
