Abstract: In general, the present disclosure is directed to compositions and processes to increase pulp yield, reduce extractives, and reduce scaling in a chemical pulping process. In one particular embodiment, for instance, the present disclosure is directed to a composition comprising a surface active agent, an alkaline mixture, at least one polymer, the polymer having a linear backbone segment having two ends, at least one phosphorus component, the phosphorus component chemically linked along the linear backbone segment of the polymer, and at least one end component, the end component chemically linked to one or both ends of the linear backbone segment of the polymer.

Abstract: Described herein are new phosphonic polymers and methods of making and using the same. The polymers are prepared by the polymerization of phosphonic acid monomers with hypophosphorous acid, an alkali metal hypophosphite, an alkyl substituted hypophosphite, or any combination thereof. The resultant polymers have pendant phosphonate groups attached to the polymer backbone as well as phosphinate groups incorporated within the polymer backbone. Additional monomers can be used to produce copolymers, terpolymers, and the like. The polymers described herein have numerous applications with respect to inhibiting scale formation and corrosion in a number of systems.
