Synthetic cationic polymers are used as promoters for alkenyl succinic anhydride sizing. The addition of certain synthetic cationic polymers that are reactive with alkenyl succinic anhydride are shown to improve the sizing efficieny of the hydrophobic, cellulose sizing material in papermaking. Synthetic cationic polymers were intended to replace starch as an effective promoter in papermaking.

Polymères cationiques synthétiques facilitant le collage de l'anhydride succinique d'alcényle. Il est démontré que l'addition de certains polymères cationiques synthétiques réagissant avec l'anhydride succinique d'alcényle améliore l'efficacité du collage de produits de collage cellulosiques hydrophobes lors de la fabrication de papier. Il est prévu que les polymères cationiques synthétiques remplacent l'amidon pour faciliter la fabrication de papier.
