Abstract

In a process and an apparatus for the continuous preparation of polymers from reaction components, in particular of copolymers of styrene and acrylonitrile, by bulk or solution polymerization, the reaction components are passed through a recycle reactor which has at least one tube bundle reactor whose tubes are in thermal contact with a liquid heat-transfer medium and which is connected to at least one static mixing element.
