Azlactone-functional membranes prepared by solvent phase inversion techniques are disclosed. Adduct membranes prepared by the reaction of azlactone-functional membranes with nucleophilic reagents are also disclosed. Both azlactone-functional copolymers and blends of azlactone-functional homopolymers or copolymers with blending polymers can be used. These azlactone-functional membranes have azlactone functionality throughout all surfaces formed ab initio into any desired shape. Membrane properties can be modified by sacrifice of some azlactone functionality via crosslinking between azlactone moieties or coupling of hydrophilic ligands.
