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