Abstract: From dielectric spectroscopy measurements on polyisoprene performed at ambient and elevated pressures, we show that the secondary relaxation has properties of the supposedly universal Johari–Goldstein β-relaxation. These properties include approximate (i.e., in order of magnitude… read more here.
