Abstract

A process for continuously performing polymerization processes, wherein monomer(s), catalysts, and initiators are added continuously to a backmixed mixing kneader (1-1.3) with a length/diameter ratio of 0.5-3.5 and backmixed therein with already reacted product, and the reacted product is simultaneously drawn off continuously from the mixing kneader (1-1.3).
