Abstract

Méthode de fabrication d'une composition de polyacrylamide dérivé du glyoxalate résistant à l'entreposage et convenable pour être utilisé à titre d'agent de renforcement pour du papier. Dans cette composition, le glyoxal est ajouté au polymère polyacrylamide de base en deux parties et un détritivore est utilisé pour les groupes aldéhydes. Les détritivores de l'aldéhyde, qui sont des adduits de choline ou un sel de choline et un monomère acrylamide facultativement substitué, peuvent être utilisés pour stabiliser les compositions de polyacrylamide dérivé du glyoxalate et pour fournir des charges cationiques supplémentaires au squelette polymère. Des compositions comprenant un mélange d'un polyacrylamide dérivé du glyoxalate résistant à l'entreposage et d'un agent de renforcement de papier polymérique peuvent être utilisées pour augmenter la force du papier, particulièrement la résistance à l'humidité du papier.
