Title (EN) ADDITIVE TO PREVENT DEGRADATION OF POLYMER MEMBRANES
(FR) ADDITIF POUR EMPÊCHER LA DÉGRADATION DE MEMBRANES POLYMÈRES
Abstract: front page image
(EN)Phosphonic acid is used as an inhibitor of free-radical degradation of polymer membranes. Also provided are hydrophilic polymers formed by the polymerisation of components including vinylphosphonic acid and another monomer, such that both components are incorporated into the hydrophilic polymer.
(FR)L'acide phosphonique est utilisé comme un inhibiteur de la dégradation par les radicaux libres de membranes polymères. Des polymères hydrophiles sont formés par la polymérisation de composants comprenant l'acide vinylphosphonique et un autre monomère de sorte que les deux composants sont incorporés dans le polymère hydrophile.
