Abstract: The present disclosure provides for a method of preparing and using an emulsion for treating a papermaking process. The emulsion is an oil-in-water emulsion of alkenyl succinic anhydride emulsified with a polymer comprising at least one primary or secondary amine containing monomer. The method comprises adding an oil-in-water emulsion to the papermaking process; wherein the oil-in-water emulsion comprises alkenyl succinic anhydride emulsified with a polymer comprising at least one primary or secondary amine containing monomer; and wherein the oil-in-water emulsion is added in an amount sufficient to improve sizing of the paper produced by the papermaking process. The primary or secondary amine may be a secondary amine comprising diallylamine, and the polymer may be a diallylamine-acrylamide copolymer.

Abstract: The disclosure provides methods and compositions for increasing the dry strength of paper. The invention utilizes a tailored strength agent whose size and shape is tailored to fit into the junction points between flocs of a paper sheet. The strength agents is in contact with the slurry for just enough time to collect at the junction points but not so much that it can migrate away from there.

Abstract: Disclosed are compositions and methods useful in applications relating to papermaking. The compositions and methods of the present invention comprise aldehyde-functionalized polymers designed to impart high paper strength and enhance water removal during the papermaking process. The aldehyde-functionalized polymers are of relatively low molecular weight, and comprise amino and/or amide groups mono-reacted and di-reacted at a ratio of at least about 1.5 to 1. The low molecular weight polymers of the present invention have the same strength and dewatering performance as corresponding high molecular weight polymers.
