Abstract
A chlorine resistant polyamide is formed from the reaction product of an amine and an acid chloride monomer wherein both the amine and the acid chloride monomer are modified with electron-withdrawing groups that exhibit sufficient activity to (i) minimize any chlorination on both the amine and acid chloride and (ii) minimize N-chlorination. A membrane is made from the polyamide for use, for example, in a desalination unit.
