A method for making a composite polyamide membrane including a porous support and a thin film polyamide layer, wherein the method includes the step of applying a polyfunctional amine monomer and a tetraacyl acyl halide monomer represented by Formula (I) to a surface of the porous support and interfacially polymerizing the monomers to form a thin film polyamide layer; wherein A is selected from: oxygen (-O-); carbon (-C-); silicon (-Si-); each of which may be unsubstituted or substituted, e.g. with alkyl groups of 1-4 carbon atoms; or a carbonyl group (-C(O)-), X is the same or different and is selected from a halogen, and Y is selected from halogen and hydroxide. |
