Equivalent Effects of Time and Temperature in the Shear Creep and Recovery of Elastomers
Keyword(s):
Abstract An explicit relationship is set forth for the time-temperature dependence of the viscoelastic phenomena in 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=[Cα/(T−b)]+Cβ. 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.
