Abstract

L'invention concerne de nouveaux terpolymères d'anhydride maléique. Les produits de l'invention sont des terpolymères d'anhydride maléique, d'acrylamide ou de méthacrylamide et d'un troisième monomère choisi entre l'octène, le styrène, ctc. Elle a trait également à des copolymères d'anhydride maléique et d'acrylamide. Un procédé nouveau utilisant un mélange d'un solvant aromatique et d'un solvant cétonique et une température d'au moins 120 degrés C rend les polymères de l'invention insolubles dans l'eau à la température ambiante. Application de la forme hydrolysée du terpolymère comme agent anti-tartre.
