SUMMARY OR ABSTRACT
Text of Note
Enhanced oil recovery has gained increasing importance for oil industry. Polymer flooding is already widely applied, most often using polyacrylamide. However, the use of this polymer is limited by its heat resistance and salt tolerance. In the present work modifications have been made to improve the performance of polyacrylamide. Cyclodextrin (CD) and its inclusion complex based on the guest-host model theory is widely used in analytical chemistry, agriculture, the pharmaceutical field, oil industry and other fields. β-CD is observed to incorporate hydrophobic molecules to form inclusion complexes selectively. In this work polyacrylamide has been modified with β-CD and other hydrophobic groups. Allyl dodecyl dimethyl ammonium bromide and allyl-β- cyclodextrin were synthesized and introduced into the polyacrylamide chain. Acrylamide homopolymer and a group of copolymers were produced by free-radical polymerization. In the copolymer, guest hydrophobic molecules and the β-CDs form inclusion complexes and contribute to an interior associative network and, therefore an increased solution viscosity. Additionally, these copolymers exhibited better water solubility compared with homopolymer due to the charged hydrophobic side group.
