Abstract
The invention relates to a method for the production of protective colloid-stabilized polymer products by means of emulsion polymerization in a reactor having an external cooling circuit, which is equipped with a pump and a heat exchanger, characterized in that the reaction mixture present in the reactor is delivered to a cooled static mixer-heat exchanger having stationary fixtures and is subsequently returned to the reactor. The invention further relates to a device for the production of protective colloid-stabilized polymer products by means of emulsion polymerization, comprising a reactor and an external cooling circuit, characterized in that the external cooling circuit is equipped with a pump and a cooled static mixer-heat exchanger having stationary fixtures.
