Abstract: Processes for imparting oil and grease resistance to paper products. In some embodiments, the process can include combining a plurality of fibers and water to produce a slurry; forming the slurry into a wet web; pressing and draining the wet web to produce a wet sheet; and drying the wet sheet to produce a dried sheet. A sizing composition and a barrier compound can independently be applied to at least one of the slurry, the wet web, the wet sheet, and the dried sheet. The sizing composition can include one or more alkenyl succinic anhydride compounds. The barrier compound can include a polyolefin dispersion, a styrene acrylate emulsion, a sucrose ester, a modified starch, styrene maleic anhydride, an ethylene acrylic acid dispersion, a styrene acrylic acid, a polyvinyl alcohol, an ethylene vinyl alcohol, or a mixture thereof. The dried sheet can have an average KIT Value of at least 3.

Abstract: Disclosed herein are compositions and methods to increase paper machine performance and enhance sizing. The compositions include a sizing agent, an emulsifier, and an aqueous component. The emulsifier may be an aldehyde-functionalized polymer. The sizing agent may be selected from rosin size, an alkyl ketene dimer, an alkenyl succinic anhydride, and any combination of these sizing agents.

Abstract: The disclosure relates to methods and compositions for enhancing the performance of a sizing agent in a papermaking process using a sizing agent enhancer. The sizing agent can be emulsified with an emulsifier and the sizing enhancer can be a polymer comprising at least one primary or secondary amine containing monomer. The method can comprise emulsifying the sizing agent with the emulsifier; and thereafter adding the emulsified sizing agent and the sizing enhancer, separately from or contemporaneously with the emulsified sizing agent, to a fiber furnish of a papermaking process. The combination of the emulsified sizing agent and the sizing enhancer improves the sizing of product paper over the use of the sizing agent without the sizing enhancer. In at least some embodiments, the emulsified sizing agent is ASA emulsified with a polymer comprising at least one primary or secondary amine containing monomer and the sizing enhancer comprises a diallylamine-acrylamide copolymer.
