Application of geometric algorithm of time-temperature superposition to linear viscoelasticity of rubber compounds

We tested usefulness of a new algorithm of time-temperature superposition to linear viscoelasticity of three kinds of rubber compounds which are conventional in rubber industries. Different from viscoelastic fluids, linear viscoelasticity of rubber compounds are usually measured by temperature-sweep test at fixed frequencies. We converted the viscoelastic data as functions of temperature to those as functions of frequency. We also investigated effect of rubber structures on their linear viscoelasticity.
