Abstract (en)
[origin: WO2010040794A1] The invention relates to a method for producing copolymers comprising acid monomer structural units and polyether macromonomer structural units, carried out in a continuous operational mode in a reactor comprising a) a body B that rotates about an axis of rotation and that comprises a reaction surface, ß) a dosing system and ?) a device for irradiating the reaction surface, wherein i) through the use of the dosing system, the components of a starting reaction composition are applied in a thin film onto an inner area of the reaction surface of the rotating body B individually and/or as a mixture such that the thin film flows over the reaction surface of the rotating body B to an outer area of the reaction surface of the rotating body B, wherein the thin film on the reaction surface is electromagnetically irradiated using the device for irradiating the reaction surface, ii) the thin film leaves the reaction surface as a reaction composition comprising the copolymer comprising the acid monomer structural units and the polyether macromonomer structural units and iii) the reaction composition is collected after leaving the reaction surface, wherein components of the starting reaction composition include an acid monomer, a polyether macromonomer and a photoinitiator.
