Abstract The complex dielectric constant of a pure molecular weight fraction of polyethyl methacrylate was determined over a frequency range of 30 to 3 × 10 5 cps. and a temperature range of −73 to 133°C. The d.c. volume resistivity–temperature behavior was also determined. The data indicate the presence of two transition regions. It is shown empirically that superposition in its present form cannot be applied to these data.
