C. in an inert organic solvent or solvent mixture is possible with recovery of the catalyst and with formation of a product having a functionality differing only slightly, if at all, from the theoretical functionality providing the reaction components monomer, catalyst and inifer are continuously introduced into a polymerization apparatus in such a way that all three components are only mixed once they are inside the apparatus, the polymer solution is continuously removed from the apparatus, the polymer solution is freed from residual monomer, unreacted inifer and from the catalyst and worked up.
