| abstract | 1507921 Membranes GENERAL ELECTRIC CO 19 March 1975 [1 April 1974] 11444/75 Heading B5B A solution containing at least 10 g. polycarbonate resin per 100 ml. casting solvent is cast into a film, desoluation allowed to take place for a predetermined time, the film and support is immersed in a quenching bath capable of dissolving the casting solvent and swelling the polycarbonate resin, removing the membrane from the bath and the quenching bath liquid is removed from the membrane. The preferred solvent is chloroform and the quenching bath may comprise either MeOH and DMF, acetone, MeOH and toluene, or MeOH and dioxan. The quenching bath liquid is removed either by washing with water and drying or by evaporation. |
