Abstract: Methods and compositions useful in papermaking and tissuemaking applications are provided. Some embodiments of the methods and compositions comprise a polyaminoamide (“PAA”) polymer functionalized with an acrylamidophenyl boronic acid and a crosslinked polyaminoamide functionalized with an acrylamidophenyl boronic acid. The methods and compositions provide useful properties for creping that include good adhesion even under excessively wet conditions, improved film uniformity, and good film durability, while maintaining good film softness and rewettability necessary for efficient runnability of the tissue machine.

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.
