Title (EN) SYNTHETIC MEMBRANE COMPOSITION COMPRISING A FLUORINATED POLYURETHANE
(FR) COMPOSITION DE MEMBRANE SYNTHÉTIQUE COMPRENANT UN POLYURÉTHANE FLUORÉ
Abstract:
(EN) Disclosed are compositions that may be useful for forming synthetic membranes, methods of forming membranes therefrom, and membranes. In an embodiment, a membrane comprises a free hydrophilic polymer and a polyurethane, the polyurethane comprising a backbone comprising the reaction product of a diisocyanate, a polymeric aliphatic diol, and, optionally, a chain extender, wherein the backbone comprises a C2-C16 fluoroalkyl or C2-C16 fluoroalkyl ether, or the polyurethane comprises an endgroup comprising a C2-C16 fluoroalkyl or C2-C16 fluoroalkyl ether.
(FR) La présente invention concerne des compositions qui peuvent servir à former des membranes synthétiques, des procédés de formation de membranes à partir desdites compositions, et des membranes. Dans un mode de réalisation, une membrane comprend un polymère hydrophile libre et un polyuréthane, le polyuréthane comprenant un squelette comprenant le produit réactionnel d'un diisocyanate, d'un diol aliphatique polymère, et, éventuellement, un extenseur de chaîne. Le squelette comprend un groupe alkyle fluoré en C2 à C16 ou un groupe éther d'alkyle fluoré en C2 à C16, ou le polyuréthane comprend un groupe terminal comprenant un groupe alkyle fluoré en C2 à C16 ou un groupe éther d'alkyle fluoré en C2 à C16.
