英文摘要: Dilute solution viscosity of fluorocarbon-containing hydrophobically modified poly(acrylic acid) was measured in aqueous solutions of various NaCl concentrations. The intrinsic viscosity ([η]) and huggins coefficient (k^H) were evaluated using Huggins equations. It is found that, at low NaCl concentration, the modified polymers exhibit values of intrinsic viscosity ([η]) and Huggins coefficient (K^H) similar to those of unmodified polymers. For both of the modified and unmodified polymers, the intrinsic viscosity decreases with increase of NaCl concentration, while the Huggins coefficient increases upon addition of NaCl. But the variation of [η] and K^H is more significant for the modified polymers, which reflects the enhancedintra and intermolecuar hydrophobic association at higher NaCl concentration.
