ccording to stress relaxation curves of phenolphthalein polyether ketone(PEK-C)at different temperatures and the principle of time-temperature equivalence equivalence
the master curve of PEK-C at arbitrary reference temperature is obtained A coupling model(Kohlrausch-Williams-Watts(KWW)is applied to explain quantitatively stress relaxation behaviour's different temperature dependence and the relationship between stress shress relaxation and yield behaviour is established through coupling model.
