The viscoelasticity of a number of polymer solutions was studied by subjecting the solutions to simple harmonic displacements in a pipe. Both water‐based and organic‐based solutions were used. Results were analyzed in terms of a modification of the operator equation of linear viscoelasticity. A three‐constant model used earlier was found to correlate most of the data. Further experiments to verify the model are suggested.
