| titleOfInvention | Process for preparing semi-permeable membranes |
| abstract | 1493654 Semipermeable membranes SUMITOMO CHEMICAL CO Ltd 4 Sept 1975 [5 Sept 1974] 36437/75 Heading B5B Membranes are prepared by exposing the surface of a mixture of a water-insoluble polymer and a water-soluble polymer and/or a watersoluble surfactant to cross-linking by a plasma and then removing the residual water-soluble polymer and surfactant by washing with water. In examples the mixture is dissolved, cast into a film and dried before treatment. The water insoluble polymers used in the examples are polyarylsulphone, polyacrylonitrile cellulose diacetate and polystyrene. The water-soluble materials used are polyethylene glycol and its monostearate derivative, polyoxyethylene cetyl ether and polyethylene oxide. |
