Abstract

L'invention concerne une composition liquide permettant de limiter le dépôt de poix dans la fabrication de la pulpe et du papier, qui comprend une solution aqueuse constituée (1) d'un guar cationique dérivé, et (2) d'un copolymère styrène anhydride maléique. L'invention concerne également un procédé permettant d'empêcher le dépôt de poix dans les systèmes de fabrication de la pulpe et du papier, ainsi que sur le matériel de fabrication du papier.
