Abstract

L’invention concerne une composition de couchage papetière comprenant notamment un agent rhéologique aqueux combinant un composé hydrophobe polyalkoxylé et un copolymère hydrosoluble préparé en présence d’un dérivé dialkylsulfosuccinate. L’invention concerne également l’utilisation de cette composition pour la préparation de papier ou de carton ainsi que cet agent rhéologique aqueux qui permet de contrôler efficacement les différentes composantes de viscosité de la sauce de couchage, tout en améliorant sa rétention d’eau.
