ANION EXCHANGE RESINS PREPARED FROM CROSSLINKED POLYSTYRENE SULFONYL CHLORIDE

摘要

Divinylbenzene-styrene copolymers are chlorosulfonated with ClSO3H (preferably in the presence of a chlorinating agent such as SOCl2), amidated with bis(dimethylaminopropyl)-amine, N-(2-aminoethyl)ethyleneurea(with hydrolysis and methylation), Me2N(CH2)3NH2, or a similar compd. and sometimes quaternized with an alkyl halide to prep. anion exchange resins contg. tertiary amine or quaternary ammonium group and, in some cases, minor amts. of SO3H group.
