Notes:
Abstract Rheological properties of a drag-reducing surfactant were investigated with the intention to find out the influence of shear rate and the duration of shear straining on the Shear Induced Structure. The ability of the surfactant to restore the broken drag-reducing network after the decrease of shear stress is well known. This property of reversible change caused by high shear at different flow conditions was compared to a more intensive mechanical straining by means of ultrasound. Observations using electronmicroscope and spectrometer are also presented.
