| titleOfInvention | Antimicrobial semipermeable membrane |
| abstract | PURPOSE: To provide an antimicrobial semipermeable membrane which has resistance to microorganisms in itself by a method wherein a polymer containing silver acrylate or silver methacrylate as a structural unit and a cellulose ester are used as materials for producing a membrane. n CONSTITUTION: A homopolymer in which part of carboxyl groups are present in the form of a silver salt structure is prepared by copolymerization. A cellulose ester, a suitable blowing agent and the polymeric silver salt and dissolved in a suitable solvent to obtain a membrane-forming liquid. The liquid is cast, for example, on a glass plate or the like and then solvent evaporation, if necessary, is conducted for a predetermined period of time, followed by immersing the cast material into water, ice water or the like to harden the material. Further, a heat treament is conducted, as required, to obtain a flat membrane or a tubular membrane. The heat treatment is usually conducted for about 5W30min at 40W100°C. The cellulose ester may be, for example, cellulose acetate or the like, the degree of esterification being about 53W63%. n COPYRIGHT: (C)1982,JPO&Japio |
