Abstract: A method for making a composite polyamide membrane comprising the steps of applying a polyfunctional amine monomer and polyfunctional acyl halide monomer to a surface of the porous support and interfacially polymerizing the monomers to form a thin film polyamide layer, wherein the method is includes at least one of the following steps: i) conducting the interfacial polymerization in the presence of a monomer comprising at least one phosphorous-containing functional group or salt thereof and an at least one amine-reactive functional group; and/or ii) applying such a monomer to the thin film polyamide layer.

Abstract: The present invention provides processes for making higher molecular weight, functionalized poly(meth)acrylamide polymer products. As an overview, the processes use (trans)amidation techniques in the melt phase to react one or more high molecular weight amide functional polymers or copolymers with at least one co-reactive species comprising at least one labile amine moiety and at least one additional functionality other than amine functionality. In practical effect, the processes of the present invention thus incorporate one or more additional functionalities onto an already formed or partially formed polymer rather than trying to incorporate all functionality via copolymerization techniques as the polymer is formed from constituent monomers. The methods provide an easy way to provide functionalized, high molecular weight poly(meth)acrylamide polymer products.
