Abstract
A method for making a composite polyamide membrane comprising a porous support and a thin film polyamide layer, wherein the method includes the steps of applying a polar solution comprising a polyfunctional amine monomer and a non-polar solution comprising a polyfunctional acyl halide monomer to a surface of a porous support and interfacially polymerizing the monomers to form a thin film polyamide layer. The method is characterized by including a substituted benzamide monomer within the non-polar solution.
