METHOD FOR MAKING MONOMERS WITH TWO QUATERNARY AMINO GROUPS AND (CO)POLYMERS OBTAINED FROM SAID MONOMERS
The invention concerns a method for preparing compound (I), which consists in introducing a quaternizing agent R - X<-> in a solution, in a organic solvent or a mixture of organic solvents, of a compound of formula (III), at a temperature between 35 to 80 DEG C, then allowing the reaction to o...

Summary: | The invention concerns a method for preparing compound (I), which consists in introducing a quaternizing agent R - X<-> in a solution, in a organic solvent or a mixture of organic solvents, of a compound of formula (III), at a temperature between 35 to 80 DEG C, then allowing the reaction to occur at said temperature until compound (III) has completely or substantially disappeared; and adding water, and then preparing an aqueous dispersion of compound (I), and eliminating water, as the case may be. R = H or -CH3; R = one among -CH3, -C2H5, -C3H7 and -C4H9; both R 's are identical or different and represent each one among -CH3, -CH2H5, -C3H7, -C4H9 and -CH2C6H5; the two X<-> are identical or different and represent each Cl<-> or Br<->.
Pour préparer le composé (I), on introduit un agent quaternisant R - X<-> dans une solution, dans un solvant organique ou un mélange de solvants organiques, d'un composé de formule (III), à une température de 35 à 80 DEG C, puis on laisse se dérouler la réaction à ladite température jusqu'à disparition complète ou sensiblement complète du composé (III), et on ajoute de l'eau, puis qu'on sépare une solution aqueuse de composé (I), et qu'on élimine l'eau le cas échéant. R = H ou CH3; R = l'un parmi -CH3, -C2H5, -C3H7 et -C4H9; les deux R sont identiques ou différents et représentent chacun l'un parmi -CH3, -C2H5, -C3H7, -C4H9 et -CH2C6H5; et les deux X<-> sont identiques ou différents et représentent chacun Cl<-> ou Br<->. |
