| Abstract: | In this article, the synthesis and characterization of a new class of macromolecule water‐soluble polymers with cyclodextrin sides were presented, which possess molecular recognition function. The polymer composed with three functional monomers was investigated through an infrared spectrometry and a scanning electron microscope. Then, the rheological properties and the interaction with surfactant of this series of polymer samples were evaluated and compared with polyacrylamide to prove that they have superior rheology performance. Also, through the adsorption experiment it can be seen that the polymer has excellent performance in polymer flooding, and it can effectively reduce over 20% of the surfactant loss caused by stratum absorption in the process of polymer/surfactant flooding. These have laid a theoretical foundation for its application to enhance oil recovery. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011 |
