  • Alkenyl succinic anhydride emulsion
    Patent number: 5176748
    Abstract: In sizing paper and paperboard with an aqueous ASA sizing system, a dispersal is formed comprising an ASA, a water-immiscible carrier, and a cationic water-soluble dispersing agent and when desired, a non-ionic surfactant. The dispersal can be shipped and stored for a prolonged time until use. The dispersal is added to water to form an oil-in-water sizing emulsion. This prepared emulsion is suitable for sizing paper and paperboard directly without the need for additional emulsifying agents or expensive equipment.
