Abstract: Emulsions of mobility control polymers can be used to increase recovery of crude oil from a subterranean hydrocarbon-containing formation. A flooding fluid comprising the polymer emulsions are injected into a well that is in contact with the subterranean hydrocarbon-containing formation. The polymers can be temporarily cross-linked via hydrolyzable crosslinking moieties derived from a multifunctional hydrazide, a multifunctional amine, a multifunctional hydroxylamine, or a combination thereof and have improved injectivity into the well; the improved injectivity can be measured in terms of the flooding fluid's filter ratio, flow rate, and viscosity.

Abstract: Methods and compositions useful in papermaking and tissuemaking applications are provided. Some embodiments of the methods and compositions include a polyaminoamide 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: 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.
