Abstract

Hydrophobically modified poly(acrylic acid) (HMPA) with single-tailed pendant side groups was prepared by precipitation polymerization. The effects of polymer concentration, surfactant and co-solvent on the solution properties of HMPA were investigated. HMPA solutions showed good viscosity enhancement and typical shear thinning behavior with increasing concentration. The surfactant TX-10 and co-solvent ethylene glycol gave rise to factors that changed the hydrophobic interactions and in turn the rheology behavior of the solutions. The transient associative network of HMPA in ethylene glycol + water mixed solutions was retained as the temperature was decreased to below 0 °C.
