Abstract: Cross-linked polymeric gels or films are prepared by dissolving in a suitable solvent a linear polymer or polymers containing pendant amidocarbonyl or oxycarbonyl groups, hydroxyl groups present as either pendant groups from the polymer or as a low molecular weight polyol, and a strongly acidic catalyst (which may also be a pendant group on a polymer). The solvent is removed by coagulation and/or drying and the dry material is heat-cured, thus cross-linking and insolubilizing the polymer or polymers.

Abstract: Pressure-driven affinity sorption membranes are prepared from a membrane filter composed of an insoluble matrix polymer or an interpolymer composite and used for separation and purification by passing therethrough solutions containing mixtures, one or more of which forms a specific complex with the ligand on the pore surface of the membrane, washing out the uncoupled solutes, then employing an appropriate displacing or eluting agent to recover the desired component in a pure and concentrated state, all under pressure-driven conditions.
