Abstract: The disclosure provides compounds, compositions, and methods for improving a papermaking process. A method may include adding a strength aid to a cellulosic fiber suspension in the papermaking process and adding a dewatering agent to the cellulosic fiber suspension. The dewatering agent may comprise a polymer having a reduced specific viscosity from about 2.5 to about 5.5 dL/g. The polymer may include, for example, a solution polymer, a latex polymer, or both. The strength aid may be selected from, for example, a cationic GPAM polymer, an anionic GPAM polymer, an amphoteric polymer with an overall negative charge, an amphoteric polymer with an overall positive charge, a cationic polyacrylamide polymer, an anionic polyacrylamide polymer, an associative polymer, a treatment polymer embedded in a colloidal hydroxide complex, starch, or any combination of the foregoing.

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.
