Solvent resistant polymeric membranes

A radiation curable composition for preparing a polymeric membrane includes a) a membrane polymer selected from the group consisting of a polysulfone (PSU), a polyether sulfone (PES), a polyether etherketone (PEEK), a polyvinylchloride (PVC), a polyacrylonitrile (PAN), a polyvinylidene fluoride (PVDF), a polyimide (PI), a polyamide (PA) and copolymers thereof; b) a hydrophobic monomer or oligomer having at least two free radical polymerizable groups independently selected from the group consisting of an acrylate group, a methacrylate group, an acrylamide group, a methacrylamide group, a styrene group, a vinyl ether group, a vinyl ester group, a maleate group, a fumarate group, an itaconate group, and a maleimide group; and c) an organic solvent for the membrane polymer and the hydrophobic monomer. A polymeric membrane and a method for manufacturing the membrane are also disclosed.
