Abstract (en)
[origin: WO9705330A1] 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.
