INVENTORS: ALBERT RENKEN, NGUYEN KHAC TIEN, FELIX STREIFF INVENTION: REACTOR FOR CONTINUOUSLY PERFORMING POLYMERIZATIONS IN HIGHLY VISCOUS MEDIA AND METHOD OF PREPARING POLYSTYRENE ABSTRACT OF THE DISCLOSURE The reactor for continuously perforning polymerizations in highly viscous media to obtain, for example, polystyrene, comprises a tube or tube structure which is subdivided to form individual sections. Static mixing elements are arranged within the tube or tube structure so as to fill the cross-section thereof. A pre-polymerizer is formed by a first tube section and a recirculation line provided with a pump which is connected to the tube or tube structure between the first section and the second section thereof and to the reactor inlet, while the second and third sections of the tube or tube structure form a plug flow reactor. The reactor is distinguished by its simple structure; local overheating and segregation are prevented therein at small energy expense by means of the static mixing elements.
