摘要
Composite solvent stable membranes for treating organic liquids comprise a crosslinked layer of less than 5 microns in thickness supported on a solvent stable porous membrane substrate, which layer includes at least one polymer selected from polyphenylene oxide type polymers and polysulfone type polymers, provided that the crosslinked layer includes at least one polymer derived from haloalkylated polyphenylene oxide type monomers. Such composite membranes include solvent stable membranes which swell to an extent of no more than about 10% when immersed in various organic solvents, and their mixtures with each other and/or water.
