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.
