    摘要: The invention relates to a process for the preparation of copolymers containing acid monomer structural units and polyether macromonomer structural units, which is carried out in a continuous mode of operation in a reactor which has α) a body B rotating about an axis of rotation and having a reaction surface, β) a metering system and γ) a device for irradiating the reaction surface, i) the components of a starting reaction composition being applied individually and/or as a mixture with the aid of the metering system in a thin film on an inner region of the reaction surface of the rotating body B so that the thin film flows over the reaction surface of the rotating body B to an outer region of the reaction surface of the rotating body B, the thin film on the reaction surface being electromagnetically irradiated by means of the device for the irradiation of the reaction surface, ii) the thin film leaving the reaction surface as a reaction composition which has copolymer containing acid monomer structural units and polyether macromonomer structural units and iii) the reaction composition being collected after leaving the reaction surface, an acid monomer, a polyether macromonomer and a photoinitiator being present as components of the starting reaction composition.
