Analysis of the master curve for the viscoelastic behaviour of polymers

A detailed analysis of typical master curves reported in the literature for the dynamic modulus and compliance of unfilled polyuretane rubber and poly(n-octyl methacrylate), respectively, and for the transient modulus of styrene-butadiene rubber is performed. It is shown that the time-temperature su...
