摘要:
An explicit relationship is set forth for the time‐temperature dependence of theviscoelasticphenomena in the superelastic polymers. An empirical equation that was found to represent adequately the above‐mentioned relationship over the entire multiple‐temperature curve is of the form: logtc= [C&agr;/(T−b)]+C&bgr;. Experimental verification is given for the equivalent influence of time and temperature on the creep and recovery of compounds based on Hevea, GR‐S, Neoprene GN, Butaprene, and butyl rubber. A comparison of the empirical equation with that of a theoretical reaction‐rate equation of Tobolsky and Eyring indicates a temperature dependence of the energy of activation.
