Abstract:
... Synthesis of a novel biodegradable hydrosoluble graft-copolymer named KGM-g-AM-g-AA-g-APEG was carried out using konjac glucomannan, acrylamide, acrylic acid, and allyl polyoxyethylene ether via free-radical copolymerization. Effective characterization methods , including XRD, TGA, FT-IR, ¹H NMR, and SEM, were adopted to evaluate the graft-copolymer. The good biodegradability of the graft-copolyme ...

Abstract:
... The current study introduces the water-soluble complexes containing hydrophobically associating copolymer and a series of surface activity imidazolium-based ionic liquids (CnmimBr, n=6, 8, 10, 12, 14 and 16). The polymer, denoted as PAAD, was prepared with acrylamide (AM), acrylic acid (AA) and N,N-diallyl-2-dodecylbenzenesulfonamide (DBDAP). And the hydrophobic associative behavior of PAAD was st ...

Abstract:
... As a non-renewable resource, the rational exploitation of oil has attracted a large amount of attention. Among many methods for enhanced oil recovery, polymer flooding is the most suitable method of chemical flooding for non-marine reservoirs and therefore various modified acrylamide-based copolymers have been studied. In this study, a novel α-aminophosphonic acid-modified hydrophobic associating ...
