a method for removing heat from a horizontal linear flow reactor , comprising introducing vapor bubbles into a liquid medium in the reactor and removing the vapor from the reactor . a method of producing an elastomer reinforced polymer comprising autorefrigerating the reactants in a horizontal linear flow reactor in which both initial polymerization and phase inversion occur . a method of removing heat from a horizontal plug flow reactor comprising aerating the reactants within the reactor , wherein the aeration promotes radial mixing of the reactants but does not substantially promote axial mixing of the reactants . a horizontal linear flow reactor , comprising a horizontal reaction chamber having one or more mechanical flow facilitators disposed therein and a sparger attached to the bottom of at least a portion of the reaction chamber .
