Title
(EN) CURABLE COMPOSITIONS AND MEMBRANES
(FR) COMPOSITIONS DURCISSABLES ET MEMBRANES
Abstract
(EN)
A process for preparing a membrane comprising applying a curable composition to a porous support and curing the composition, wherein the composition comprises: a)a curable ionic compound; b)a first crosslinking agent; c)a second crosslinking agent; d)an inert solvent; and e)optionally a free radical initiator; wherein the second crosslinking agent has a melting point below 80°C. Also claimed are the compositions and membranes obtainable by using the process.
(FR)
La présente invention concerne un procédé de préparation d'une membrane comprenant l'application d'une composition durcissable sur un support poreux et le durcissement de la composition, la composition comprenant : a) un composé ionique durcissable; b) un premier agent de réticulation; c) un second agent de réticulation; d) un solvant inerte; et e) éventuellement un initiateur de radicaux libres; le second agent de réticulation ayant un point de fusion inférieur à 80 °C. L'invention concerne également des compositions et des membranes pouvant être obtenues à l'aide dudit procédé.
