The time-temperature superposition principle is used to obtain generalized compliance curves for predicting the long-term isothermal creep of low-density polyethylene. It is established that the long-term creep is predicted with an accuracy at least 16% (P=0.99) with a reduction in test duration by a factor of more than 50. An attempt is made to extend the time-temperature superposition principle to include estimates of the nonisothermal compliances associated with thermal cycling based on the isothermal curves. It is shown that this method is not accurate enough to predict the long-term nonisothermal creep, the discrepancy being statistically significant and increasing with time.
