Abstract
A microchannel polymerization reactor comprising: (a) a first microchannel adapted to carry a reactant stream; (b) a fluid conduit adapted to carry a fluid in thermal communication with the first microchannel; and (c) a static mixer in fluid communication with the first microchannel adapted to provide a mixing zone operative to change the cross-sectional fluid flow profile at a predetermined point along the first microchannel without changing the primary direction of the reactant stream through the first microchannel. The present invention also includes a method of carrying out a polymerization reaction within a microchannel reactor comprising: (i) directing at least one of monomer, initiator, water, surfactant, coagulant, and solvent into a reactant stream and into contact with reactant flowing within a first microchannel to initiate a polymerization reaction occurring within a first microchannel; and (ii) mixing the reactant of the reactant stream by positioning at least one static mixer in series with the reactant stream, where the static mixer is adapted to change a cross-sectional fluid flow profile of the reactant stream flowing through the first microchannel without changing…
