Abstract

The rheological properties of low molecular weight (LW) and high molecular weight (HW) hydrophobically modified hydroxyethylcellulose (HMHEC) have been studied in semi-dilute regime of concentration (C>C*) and compared with their unmodified parent polymers (HEC). Flow behavior and viscoelastic properties of modified polymers as a function of salt (NaCl, KSCN), temperature (20–60°C) and shear rate (0.1–1000 s−1) are explained by the existence of hydrophobic interactions. These latter are reinforced in the presence of water structure makers (NaCl).
