Process for manufacturing the chloride of 1,3-bis- (dimethylbenzylammonium) isopropyl, acrylate alone or mixed with other monomers, and corresponding (co) polymers

摘要

A compound of formula (I) is prepared alone or in combination with at least one monomer of formula (II): the quaternizing agents benzyl chloride is introduced into a solution, in a solvent selected from compounds of the formulae (I) and (II) and mixtures of these, of the compound of formula (III) at a temperature of from 35 to 60° C., and then water is added and the reaction is allowed to proceed to complete or substantially complete conversion of the compound (III), an aqueous solution of desired compound (I) is isolated where appropriate with at least one compound (II), if this or these have/has been used as solvent, and the water is removed where appropriate.
