Abstract
The present invention relates to pulverulent water-swellable hydrophilic (co)polymers which comprise, for reducing dusting, auxiliaries from the series consisting of silicones and/or other auxiliaries, the latter in a total amount of less than 1% by weight, for example polyglycols or polyglycol ethers, the vapor pressure of the individual auxiliaries being not more than 0.1 mbar at 20.degree. C. and their melting point being not more than 100.degree. C., processes for their preparation and their use for absorption of water and aqueous solutions.
