Tailored copolymers structures: Effect on drag reduction in aqueous media
- Univ. of Southern Mississippi, Hattiesburg, MI (United States)
Water soluble polyampholytes as well as hydrophobically associating copolymers based on acrylamide (AM), sodium 2-(acrylamido)-2-methylpropanesulfonate (NaAMPS), 2-(acrylamido)-2-methylpropanetrimethylammonium chloride (AMPTAC), sodium 3-acrylamido-3-methylbutanoate (NaAMB), 3-(2-acrylamido-2-methylpropanedimethylammonio)-1-propanesulfonate (AMPDAPS), and N-isopropylacrylamide (IPAM) have been synthesized and thoroughly characterized. The drag reduction properties were measured on a rotating disk rheometer. The relative drag reduction efficiencies have been reported in terms of absolute drag reduction (DR) as well as parameter, {Delta}, that has been obtained through volume fraction normalization (from a plot of %DR/{eta}C vs {eta}C.). This {Delta} parameter has also been correlated with other parameters reported in literature which bring out the effect of polymer structure and composition on drag reduction.
