Factors Influencing Viscosity of Twin-Tail Hydrophobically Associating Polymer Weak Gel


Article Preview

Weak gel was sythysized by twin-tail hydrophobically associating polymer P(AM/ DiC6AM/NaAA) crosslinked with water-soluble phenolic resin. Apparent viscosity of week gel increases with the increasing of polymer concentration and the increasing of phenolic resin. The crosslinking reaction is influenced by salt. Apparent viscosity of week gel firstly increased and then decreased with increasing salt concentration. Weak gel has shear thinning property. But apparent viscosity of weak get is recoverable after shear.
