    Abstract: It is possible to remove quantities of heat from exothermically running polymerization reactions of vinyl monomers in heterogeneous phase, in a sophisticated manner by adding liquids to the reaction medium for the removal of heat and to regulate the reaction temperature, which liquids do not dissolve the polymer under the reaction conditions and the boiling temperatures of which are lower than or are identical to the technically predetermined reaction temperatures under the polymerization conditions which are applied, and the heat which is released in the reaction system is removed by evaporating these liquids.
