Abstract
A halogen resistant polyamide is formed from the reaction product of an amine monomer and an acid chloride monomer wherein the amino group of the starting amine monomer is separated from the aromatic amine ring system by an alkyl group and (i) minimizes halogenation on the amine and (ii) minimizes N-halogenation at a pH range of approximately 7 to approximately 10.5. A membrane is made from the polyamide for use, for example, in a reverse osmosis desalination unit.
