PROCESS FOR THE MANUFACTURE OF 1,3-BIS ACRYLATE CHLORIDE (DIMETHYLBENZYLAMMONIUM) ISOPROPYL ALONE OR A MIXTURE OF OTHER MONOMERS AND (CO) POLYMERS THEREOF

摘要

P A compound of formula (I) is prepared alone or in combination with at least one monomer of formula (II): the quaternizing agent benzyl chloride is introduced into a solution, in a solvent chosen from the compounds of the formulas ( I) and (II) and their mixtures, of the compound of formula (III) at a temperature of 35 to 60 ° C., then water is added and the reaction is allowed to proceed until complete or substantially complete conversion of the compound ( III), an aqueous solution of the desired compound (I) is separated if necessary with at least one compound (II) if this or these have been used as solvent, and the water is eliminated if necessary. (CF DRAWING IN BOPI) R = -CH3 or -CH2 C6 H5. /P
