Abstract

Procédé de formation de polymères d'acide hydroxamique fortement anioniques selon lequel on estérifie des polymère d'acide (méth)acrylique dans une solution aqueuse pour former des poly(méth)acrylates. On fait ensuite réagir les polymères résultant avec une hydroxylamine pour produire des polymères hydroxamatés contenant de l'acide (méth)acrylique. On décrit également dans cette invention les polymères estérifiés, leurs dérivés hydroxamatés et leur utilisation pour floculer des écoulements du procédé Bayer.
