Abstract
Anion-exchange resins made by aminoalkylating an alkylatable resin in solvent-swollen condition with bis-carboxyimidomethyl ethers in a reaction mixture containing essentially unhydrated SO.sub.3 that can be added in the form of a solution in H.sub.2 SO.sub.4 or other solvent or as a complex with the alkylating ether, or in undissolved condition. The acylaminoalkylated product thus formed is deacylated as by hydrolysis and can have the resulting amino group alkylated and even quaternized.
