Water-swellable, hydrophilic polymer compositions 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.

Compositions polymériques hydrophiles, gonflables à l'eau. La présente invention porte sur des compositions polymériques hydrophiles, gonflables à l'eau, pouvant être préparées grâce à la (co)polymérisation par des radicaux libres d'un ou de plusieurs monomères hydrophiles en présence d'amidon et (ou) d'amidon modifié chimiquement, avec utilisation d'un radical libre formant trois ou plusieurs sites de radicaux libre par molécule.
