Abstract:
1. An apparatus for producing an isoolefin-diolefin rubber comprising: (a) a reaction vessel comprising an impeller for preparing a slurry of an isoolefin-diolefin rubber in a liquid non-aqueous reaction medium at a temperature in a range of from −110° C. to −50° C., said reaction vessel having an outlet; (b) an expression separator in fluid communication with the outlet of the reaction vessel for separating at least part of the liquid non-aqueous reaction medium in the liquid form from the rubber; (c) a slurry processing vessel in fluid communication with the expression separator for receiving residual slurry; and, (d) a conduit in fluid communication with the expression separator at one or more points between the reaction vessel and the slurry processing vessel for transporting the liquid non-aqueous reaction medium separated in liquid form from the rubber by the expression separator out of the expression separator and away from the reaction vessel.
