A new method for preparation of hydrophilic fillers has been found, based on high-molecular weight compounds insoluble in water, obtained by the copolymerization of unsaturated monomers, soluble and insoluble in water, either in the form of an aqueous emulsion containing 10-70% by wt. of fillers, or in the dry powdered form having the required particle size, which in the final application are able to sorb reversibly water vapor, and are particularly suited for producing synthetic leather and similar materials.
