DILUTE SOLUTION PROPERTIES OF DRAG REDUCING POLYMERS

Abstract

Experimental data on the dilute solution viscosity behavior of two effective drag reducing polymers (polyethylene oxide-Polyox and Separan - a partially hydrolyzed polyacrylamide) in various solvents (distilled water, salt water and simulated sea water) is presented and discussed. The unusual viscosity behavior observed for both polymers in the simulated sea water for concentrations less than thirty parts per million is explained by postulating an interchain ionic bonding effect for the Separan solutions and a ion-dipole, salt-polyether complex formation in the Polyox solutions. Tentative conclusions concerning the effectiveness of the polymers as drag reducers in the solvents and concentrations tested are presented.
