Abstract: The invention relates to a method for producing aqueous solutions of homo or copolymers of acrylic acid by means of radical polymerization of acrylic acid and optional water-soluble, monoethylene unsaturated comonomers in an aqueous medium in the presence of at least one water-soluble initiator and at least one water-soluble regulator, wherein the polymerization is performed by means of a continuous process, and wherein low-molecular components are at least partially separated out of the aqueous polymer solution obtained after polymerization. Microstructured mixers and reactors are preferably used for the polymerization. At least one reactor and/or mixer having microstructures are preferably used for the process.
