Abstract
The present invention relates to a continuous process for the production of polymeric coupling products by using a reactor assembly which is equipped with two or more reaction cells. The educt fluid is pumped through the reaction cells and thoroughly mixed therein by means of agitators. Preferably the process according to the invention is used for the preparation of coupling products which show at least partially precipitation and/or gelation effects during the performance of the synthesis. The precipitation and/or gelation effects are associated with and increase of the viscosity of the reaction system under reaction conditions. The products which are obtained by the process according to the invention have increased molecular weight and low polydispersity over similar products which were obtained in batch experiments.
