✦ Synopsis

Results from a series of rheological and pipe flow experiments using watersoluble hydroxyethylcellulose and polyethyleneoxide are presented. Phenomena of drag reduction were investigated for values of concentration (in weight) of polymers in water ranging 2=10 4 to 2=5.10 -3. Velocity measurements by using a laser-Doppler anemometer to type DISA-Mark II served for determining the variation in thickness of the elastic sublayer in the turbulent flow exhibiting drag reduction.

## Abstract The intrinsic viscosity of dilute solutions containing flexible chain macromolecules flowing in a velocity field with parallel gradient has been analyzed. It has been found that the viscosity at rest is three times the value of the shearing viscosity. The viscosity increases monotonical
