摘要： A porous membrane is formed from an interpenetrating polymer network of a hydrophobic polymer and a polymerized and crosslinked hydrophilic monomeric composition. A solution of the polymer and monomeric composition is cast, exposed to ultraviolet radiation, coagulated and dried. The resulting dried membrane is annealed in order to render its surface hydrophilic.

摘要： A porous membrane, such as a microporous or ultrafiltration membrane, is formed from a solution of a polysulfone and a free radical polymerizable monomer exposed to ultraviolet light to form a blend of the polysulfone and copolymers of polysulfone activation products and polymerized monomer having polymer segments covalently bonded to each other. The solution is separated into two phases including a porous solid phase comprising the membrane.

摘要： A composite membrane and process utilizing the membrane which is capable of selectively removing particles such as viral particles from a solution such as a protein solution is provided. The membrane comprises a porous membrane substrate, a surface skin having ultrafiltration separation properties and an intermediate porous zone between the substrate and the skin which intermediate zone has an average pore size smaller than that of the substrate. The intermediate zone is free of voids which break the skin and which directly fluid communicate with the substrate. The composite is capable of a log reduction value of at least 3 (99.9% removal) of particles selectively from solution.
