We use the spin line method, which is developed by Jones et al., to measure the extensional viscosity of polymer solutions and suspensions of fine particles in polymer solutions. From the velocity profiles obtained it is found that a uniaxial extensional flow is nearly attained in this experiment. We show that all the solutions of PAA are tension-thickening and the extensional viscosity in the suspensions is affected by the concentrations of both polymer and suspended particle.
