PROCESS FOR THE BULK POLYMERIZATION OF ALKENYLAROMATIC COMPOUNDS

摘要

of the disclosure: There is described a process for the homopolymerization or copolymerization in the bulk of alkenylaromatic compounds in a continuous flow agitation vessel. The feed of the monomer(s) is preheated and a controlled larger or smaller part of the preheated monomer feed is cooled, depending on the deviation of the temperature of the contents of the reaction vessel from the determined value. The inventive process ensures an improved constancy of the reaction temperature, and, consequently, of the molecular weight of the polymer obtained.
