Abstract:
A continuous process for preparing polymers comprising:continuously feeding at least one reaction mixture containing at least one monomer to at least one non-cylindrical channel; continuously controlling the temperature of the at least one non-cylindrical channel by exposing the surface of the at least one non-cylindrical channel not exposed to the at least one monomer to a temperature control medium; polymerizing the at least one monomer in the at least one non-cylindrical channel by emulsion polymerization or suspension polymerization; and continuously removing the polymer from the at least one non-cylindrical channel; wherein the rate at which the at least one reaction mixture containing the at least one monomer is fed to the at least one non-cylindrical channel containing the polymer is controlled, such that the amount of the at least one monomer in the at least one non-cylindrical channel does not exceed the amount that can be swollen into the polymer in the at least one non-cylindrical channel.
