TURBULENT DRAG REDUCTION BY POLYACRYLIC ACID

Polyacrylic acid was synthesized to high molecular weight, then studied as a drag reducing agent in dilute solutions of variable pH and ionic strength, the polymer being in both non-ionized and polysalt forms. As the polymer varies from the non-ionized polycarboxylic acid in the form of a compact coil at pH 2 to the polycarboxylate salt in the form of a very highly extended coil in solutions of low ionic strength, its effectiveness in drag reduction continuously increases.
