AbstractThe stress–relaxation modulus of an unfilled ethylene vinyl acetate polymer at three different degrees of crosslinking was measured at 15 temperatures over a temperature span of about 160°C. At each temperature, the time response was measured for at least 3 decades of time. From these data it was possible to construct a master curve for each degree of crosslinking. The time–temperature shift factors,aT, were found to be related to temperature by the relation logaT= −A(T–273), where the parameterAhas an average value of 0.234 for the three m
