Abstract

Pour préparer ces polymères présentant des motifs au hasard, de formule (I), on fait réagir dans un solvant commun, à une température d'au moins 100 degrés C, un polymère (II) de poids moléculaire d'au moins 500, ayant des groupes fonctionnels amide pendants, et un réactif chimique (III), le rapport molaire de (III) aux groupes amide pendants de (II) étant entre 5 : 1 et 1:100. Ces polymères sont utiles comme dispersants (traitement des eaux), agents anti-tartre, floculants et coagulants.To prepare these polymers having random units, of formula (I), a polymer (II) of molecular weight of at least 500, having pendant amide functional groups, and a chemical reagent (III), the molar ratio of (III) to the pendant amide groups of (II) being between 5: 1 and 1: 100. These polymers are useful as dispersants (water treatment), anti-scale agents, flocculants and coagulants.
