Patent

CA 2605499

The present invention relates to a water-swellable hybrid material comprising a structurally crosslinked polymer matrix and inorganic particulate solids bound therein, having a time-dependent swelling behaviour corresponding to an uptake of water of at least 7.5 times the hybrid material~s own weight within one hour, and also to its uses. The present invention further relates to a process for preparing this water-swellable hybrid material.

L'invention se rapporte à un matériau hybride pouvant gonfler à l'eau comprenant une matrice polymère présentant une structure réticulée, ainsi que des particules solides inorganiques qui sont fixées à l'intérieur de cette matrice polymère. Le gonflement du matériau hybride se fait en fonction du temps et correspond à une absorption d'eau égale à au moins 7,5 fois le poids propre du matériau hybride en l'espace d'une heure. Cette invention concerne en outre les utilisations dudit matériau hybride, ainsi qu'un procédé de production de celui-ci.
