The parabolic law, according to the equation , of the elasticity in the relaxation phenomena of molten polymers can be deduced from the consideration of the feature that the experimental stress relaxation curves show log–log plots which are often linear in a broad field. A general analysis, only on the basis of the viscoelastic equation permits calculation of relaxation functions, which are suggested as possible means of polymer characterization.
