Beschreibung
Zusammenfassung:	The water dispersibility of water-soluble polymer particles can be improved by a method which comprises the following step: i) foaming a fluid composition comprising a compound A) having a weight average molecular weight of less than 10,000 or a water-insoluble polymer B) having a weight average molecular weight of at least 10,000; ii) contacting the produced foam with water-soluble polymer particles having a weight average molecular weight of at least 10,000; and iii) drying the particles, whereby the foam collapses during the contacting and/or drying step and the water-soluble polymer particles are encrusted with the compound having a weight average molecular weight of less than 10,000 or the water-insoluble polymer having a weight average molecular weight of at least 10,000.
