Patent ID: 8754139

Claim:
A polymeric membrane comprising an active layer that is on a support, wherein the active layer comprises a polymer with a backbone having attached thereto at least one fluoroalcohol moiety, wherein the polymer in the active layer is derived by reacting a chemical mixture (A) and a chemical mixture (B), wherein (A) and (B) are immiscible with each other, and wherein: (A) is an aqueous base comprising a monomeric polyamine reactant having one or more hexafluoroalcohol groups represented by Formula 1: wherein R 0 represents an organic group selected from the group consisting of aliphatic, alicyclic, aromatic, heterocyclic groups and combinations thereof, m is an integer of 2 or more, and n is an integer of 1 or more, and (B) is organic, and comprises a monomeric polyfunctional acyl halide reactant represented by Formula 2: R 1 COX) p Formula 2 wherein R 1 represents an organic group selected from the group containing aliphatic alicyclic, aromatic, heterocyclic groups and combinations thereof, X is selected from the group consisting of fluorine, chlorine, bromine and iodine, and p represents an integer of 2 or more.
