POLYMERIC AROMATIC N-HALO SULFONAMIDES

摘要

A polymer comprises a monomer having a N-halo sulfonamide pendant group and having the formula: wherein A is a trivalent linkage; wherein Q is a divalent linkage and y is 0 or 1; wherein R₁, R₂, R₃, and R₄ are as described within; wherein X is halogen; and wherein M is an alkali or alkaline earth metal. In specific embodiments, R₁, R₂, R₃, and R₄ are hydrogen; X is chlorine; and M is sodium or potassium.
