SOLVENT RESISTANT THIN FILM COMPOSITE MEMBRANE AND ITS PREPARATION

摘要

The present invention relates to improved methods for synthesis of thin film composite membranes by interfacial polymerization. More in particular, the method of the present invention comprises the impregnation of an ultrafiltration porous support membrane with an aqueous solution containing a polyfunctional nucleophilic monomer, and contacting the impregnated support membrane with a second largely water-immiscible solvent containing a polyfunctional epoxide monomer.
