Abstract:
Method for coagulating an aqueous polymer dispersion, where the aqueous polymer dispersion comprises at least one polymer in dispersion in aqueous phase, and also comprises thermally expandable, thermoplastic microspheres, the polymer dispersion is coagulated by energy input, and the coagulated composition is delivered via an outlet aperture, preferably in the form of a nozzle.
