Method of manufacture of the chloride of the acrylate of 1,3 - bis (dimethylbenzylammonium) isopropyl alone or in mixture with other monomers and (co) polymers corresponding

摘要

A compound of formula (i) alone or in combination with at least one monomer of formula (ii) are introduced the quaternizing agent benzyl chloride in a solution, in a solvent chosen from among the compounds of formulae (i) and (ii) and their mixtures, the compound of formula (iii) at a temperature of 35 to 60degrec, and water is then added and the reaction is allowed to take place until complete conversion to or substantially all of the compound (iii), is separated from an aqueous solution of the desired compound (i), if appropriate, with at least one compound (ii), if it is used that - treatment or those - latter as a solvent, and the water is removed, if appropriate.
