Title (EN) METHOD OF MAKING POLYMERS CONTAINING HYDROXAMATE FUNCTIONAL GROUPS
(FR) PROCEDE DE PRODUCTION DE POLYMERES CONTENANT DES GROUPES A FONCTIONNALITE HYDROXAMATE
Abstract: front page image
(EN)A process is disclosed for the formation of highly anionic hydroxamic acid polymers whereby (meth)acrylic acid polymers are esterified in aqueous solution to poly(meth)acrylates. The resultant polymers are then reacted with an hydroxylamine to produce hydroxamated (meth)acrylic acid containing polymers. The esterified polymers, their hydroxamated derivatives and their use to flocculate Bayer Process streams are also disclosed.
(FR)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.
