  • Method and apparatus for phase separated synthesis
    Patent number: 6429268
    Abstract: An apparatus and method for a continuous phase-separated synthesis of particulates, and in particular an apparatus and method for a continuous polymerization which utilizes a reactor vessel having stationary annular baffles through which an aqueous medium is circulated, and to which a monomer and initiator are added. During polymerization, as the fluid circulates through the reactor vessel, the eddies created by the baffles enhance a thorough and even mixing of the fluid.
