Rheological properties of modified cellulosic polymers in semi-dilute regime: Effect of salinity and temperature

Abstract : The rheological properties of low molecular weight (LW) and high molecular weight (HW) hydro-phobically modified hydroxyethyl-cellulose (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 (NaC1, KSCN), temperature (20-60 °C) and shear rate (0.1 1000 s-a) are explained by the existence of hydrophobic interactions. These latter are reinforced in the presence of water structure makers (NaCl).
