Abstract:A series of new amphoteric block bipolymers were prepared by the functionalization of PEO−PPO−PEO block bipolymers with a terminal tertiary amine and subsequently, with acrylic acid derivatives by means of Michael reaction. In addition to the chemical process mentioned earlier, the amphoteric block bipolymers were characterized by 1D and 2D nuclear magnetic resonance, size exclusion chromatography, and thermo-gravimetric analysis. Afterward, the dehydrating capacity of the new demulsifiers was evaluated in thr… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
