Abstract: A continuous process for preparing polymers is disclosed. The continuous process includes the steps of continuously feeding a reaction mixture containing a monomer into a non-cylindrical channel, continuously controlling the temperature of the non-cylindrical channel by exposing the surface of the non-cylindrical channel not exposed to the monomer to a temperature control medium, polymerizing the monomer in the non-cylindrical channel, and continuously removing the polymer from the non-cylindrical channel. The continuous process is suitable for the preparation of polymers containing ethylenically unsaturated monomers as polymerized units by emulsion polymerization, solution polymerization, and suspension polymerization.
