Hydrophobically Modified Sulfonated Polyacrylamides for IOR: Correlations between Associative Behavior and Injectivity in the Diluted Regime

Résumé — Polyacrylamides sulfonés modifiés hydrophobes pour la RAH (IOR) : corrélations entre le caractère associatif et l’injectivité en régime dilué — Nous présentons de nouvelles corrélations expérimentales entre l’injectivité dans des membranes de polycarbonate et le caractère associatif de Polymères Hydrosolubles Modifiés Hydrophobes (PHMH) ayant des squelettes de polyacrylamide sulfoné (P...

Hydrophobically Associating Polymers for Oilfield Applications

Recent developments in water-soluble hydrophobically associating polymers are examined with particular emphasis on their use for oilfield applications. These polymers have potential for use in EOR, acidizing, drilling fluids, completion fluids and profile modification. They have also been reported to selectively reduce water permeability in sandstones, and have been used as drag-reducing agents...

Stabilized by a Hydrophobically Modified Inulin Surfactant

Hydrophobically modified chitosan gauze: a novel topical hemostat.

BACKGROUND Currently, the standard of care for treating severe hemorrhage in a military setting is Combat Gauze (CG). Previous work has shown that hydrophobically modified chitosan (hm-C) has significant hemostatic capability relative to its native chitosan counterpart. This work aims to evaluate gauze coated in hm-C relative to CG as well as ChitoGauze (ChG) in a lethal in vivo hemorrhage mode...

Hydrophobically Modified Celluloses as Novel Cholesterol-lowering Polymers

Hydrophobically modified celluloses were prepared by the esterification of monocarboxycellulose (MCC) and carboxymethylcellulose (CMC) with methanol, followed by the amino-de-alkoxylation of the methyl esters with n-octadecylamine. These cellulose derivatives were fed at 30 and 60 g/kg for 4 weeks to female rats. The diets were supplemented with palm fat (60 or 50 g/kg) and cholesterol (0 or 10...
