ABSTRACT:
Methacrylamidopropyltrimethylammonium chloride or its free amine, dimethylaminopropylmethacrylamide, is purified by contacting aqueous solutions of the salt or the free amine with solid, nonionic organic resins. Such resins absorb the organic impurities, yet leave behind the polymerization inhibitor.
