Abstract:
A polymeric membrane having maleic anhydride residues which comprises a blend of a maleic anhydride copolymer and a support polymer, said blend being partially cross-linked with a bifunctional cross-linking reagent. When hydrolyzed, this membrane turns into an ion exchange membrane or a membrane on which an enzyme is immobilized.
