Abstract

La présente invention concerne l'utilisation d'au moins une hydroxylamine de formule générale (I) : dans laquelle R1 et R2 représentent chacun indépendamment un radical alkyle en C1-C8, un radical alkyle en C1-C16 substitué par au moins un radical hydroxyle, aryle, aralkyle ou alkaryle, l'un parmi R1 et R2 pouvant en outre représenter hydrogène, comme agent destructeur de polymères hydrophiles sous forme d'hydrogels ou de suspensions aqueuses d'hydrogels. La présente invention concerne également le procédé de destruction de polymères hydrophiles sous forme d'hydrogels ou de suspensions aqueuses d'hydrogels.
