摘要： The disclosure relates to processes, related polyacid polymers, and related articles for functionalizing a porous membrane by contacting the membrane with a polyacid polymer at low pH to stably adsorb a polyacid layer on the membrane pore surface, in particular polyacid polymers including repeating units with a pendent metal-binding ligand or star polyacid polymers. The resulting functionalized membrane is characterized by a high density of free acid groups, resulting in a higher specific capacity for its intended application. The process allows functionalization of porous membranes in a very simple, one-step process, for example without a need to derivatize an adsorbed polyacid layer to impart metal-binding ligand functionality thereto. Such functional membranes may find multiple uses, including rapid, selective binding of proteins for their purification or immobilization.

摘要： A membrane process is provided for separating light olefins from light paraffins to produce a polymer grade light olefin product stream that is about 99.5 mol % ethylene or propylene. The process involves multiple stages to achieve the high purity product and provides for processing hydrocarbon streams that have differing concentrations of light olefins.

摘要： A permeable microcapsule embedded fabric acts as a sorbent that creates mold-able, variable geometry fabrics for static or dynamic use. The fabric is composed of micro encapsulated solvent spheres held together by structural members. The fabric provides an excellent means to absorb and separate gases and/or liquids, particularly to separate carbon dioxide from flue gases.

摘要： Membranes, methods of making the membranes, and methods of using the membranes are described herein. The membranes can comprise a gas permeable support layer, optionally an inorganic layer disposed on the support, and a selective polymer layer disposed on the inorganic layer. In some cases, the selective polymer layer can comprise an amine-containing polymer and an amino acid salt dispersed within the amine-containing polymer. In other cases, the selective polymer layer comprises a sterically hindered amine-containing polymer, such as a sterically hindered derivative of polyvinylamine. The membranes can be used, for example, to separate gaseous mixtures, such as flue gas.
