FIELD: chemical industry. SUBSTANCE: chemistry of polymers, more particularly technology of granulation and dehydration of aqueous polymer solutions. Grinding is carried out after freezing. Granules are subjected to treatment in organic solvent. The organic solvent is acetone. Polyacrylamide is frozen in any volumes. Dehydrated granules are blown off with air at room temperature. EFFECT: more efficient preparation method. 4 cl
