Abstract

A process offers a time-saving and cost-effective method for the continuous synthesis of terminally functional polymers through the use of efficient termination reagents from the group encompassing oxiranes, sulphur-containing oxirane analogues and nitrogen-containing oxirane analogues. The continuous process allows the introduction of different functional groups. Within a relatively short time, the properties of the polymers, such as general chemical composition, molecular weight, polydispersity, chemical composition and functionalization of the chain end, and chemical composition of the end groups, can be varied within a wide range. The polymers obtained in accordance with the invention are particularly suitable as a dispersion reagent for the mixing or stabilization of two materials which differ in mixing behaviour. Coating materials are a further possible application, for the adjustment of surface properties or the adaptation of rheological properties of viscous materials.
