A filament stretching extensional rheometer and capillary breakup extensional rheometer are used to measure the extensional rheology of a series of wormlike micelle solutions experiencing a uniaxial elongational flow. The experiments are performed using a series of wormlike micelle solutions of both cetylpyridinium chloride and sodium salicylate NaSal in an aqueous sodium chloride solution and ...

Abstract Different microstructures of the same polymer-modified bitumen (PMB) were obtained by subjecting modified with styrene-butadiene-styrene (SBS) copolymer to isothermal annealing at various temperatures. The effects morphology on rheological properties SBS-modified investigated within high-temperature range. PMB quantitatively evaluated using image analysis. A dynamic shear rheometer was...
