master curve

https://doi.org/10.1351/goldbook.12784
Viscoelastic spectrum of a polymer or polymer material constructed using the time–temperature superposition (TTS) principle, so that the spectrum covers a wide range of lengths of time or frequencies of measurement.
Note: A master curve is usually constructed by superimposing a sequence of isothermal measurements of a viscoelastic property vs. time.
