Abstract
The process for carrying out a polymerization in a tube reactor (1) comprises the following steps: Freshly introduced monomer (M) is mixed with a returned monomer-polymer mixture. The mixture is cooled to a prescribed initial temperature (heat exchanger 4). A polymerization starter (S) which is inactivatable upon heating above a decomposition temperature is admixed. A partial polymerization takes place in the tube reactor. The mixture leaving the tube reactor is heated up to at least the said decomposition temperature (heat exchanger 2). Finally, a portion of the mixture is returned (pump 3) and the other portion removed as product (P).
