Abstract: The present disclosure provides methods and compositions for strengthening paper. The methods may include a step of spraying an anionic polymer onto a paper sheet to increase the strength of the paper sheet. The anionic polymer may have amino groups, amide groups, or a combination of amino groups and amide groups. These groups may be functionalized with an aldehyde. Methods may also include a step of adding a wet end composition to a wet end of the papermaking process.

Abstract: The disclosure provides an associative polymer, a powder, a process for forming a paper sheet, and a process for making a powder. One or more associative polymers and one or more optional surfactants may be networked to form a wet gel and a powder may be formed from the wet gel. The associative polymer may have a weight average molecular weight of from about 10 kDa to about 2,000 kDa. A method may involve adding the powder to a cellulose fiber slurry, draining the cellulose fiber slurry to form a fiber pad, and drying the fiber pad to form a paper sheet.

Abstract: The present application is directed to creping adhesives. The adhesive forms from a solution/dispersion of a polyelectrolyte complex that is composed of a mixture of one or more cationic polyelectrolytes, and one or more anionic polyelectrolytes. This adhesive complex offers several desirable features when compared to conventional, non-complex adhesives such as improved coating durability, wet tack and tunable coating softness, which are key properties for an adhesive to function as a creping adhesive.

Abstract: Methods and compositions for improving performance of flocculants in an industrial production process. Methods include pH triggered cross-linking reaction between a flocculating agent, such as dextran, and a composition comprising a boronic acid-containing polymer. The pH trigger can be provided by a fluid having a pH of 8 or more. The production process can be a Bayer Process and the fluid is caustic liquor or slurry in the fluid circuit of the Bayer, wherein the reaction time is reduced over conventional methods and the cross-linked dextran composition effectuates improved flocculation of the trihydrate particles.
