ABSTRACT:
The present invention relates to water-swellable, hydrophilic polymer compositions which can be prepared by free-radical (co)polymerization of one or more hydrophilic monomers in the presence of starch and/or chemically modified starch, wherein a free-radical initiator which forms three or more free radical sites per molecule is used.
