Reduction of polymer fouling on reactor surface in a continuous process for preparing polymers

A continuous process for preparing polymers in a non-cylindrical heat exchanger is disclosed. The amount of monomer fed and polymer in the reactor is controlled to minimize fouling of the reactor. The use of steam to control the temperature of the reaction mixture is also disclosed.
