Title (EN) METHODS OF MAKING ACRYLAMIDE-ACRYLIC ACID COPOLYMERS
(FR) PROCÉDÉS DE PRODUCTION DE COPOLYMÈRES D'ACRYLAMIDE ET D'ACIDE ACRYLIQUE
Abstract:
(EN) A method of making acrylamide-acrylic acid copolymers in water-in-oil latices is described. The method results in a copolymer having randomly distributed carboxylate functionalities and is suitable for ionic crosslinking. The copolymers and their ionically crosslinked counterparts are useful for enhanced oil recovery processes.
(FR) La présente invention concerne un procédé de production de copolymères d'acrylamide et d'acide acrylique dans des réseaux eau dans l'huile. Le procédé permet d'obtenir un copolymère ayant des fonctionnalités carboxylate réparties de façon aléatoire et est approprié pour la réticulation ionique. Les copolymères et leurs contreparties réticulées par voie ionique sont utiles pour des traitements de récupération du pétrole améliorés.
