Effect of pressure on the dielectric relaxation of poly-n-butyl methacrylate
Abstract
The dielectric properties of poly-n-butyl methacrylate have been studied over a range of frequency, temperature and pressure. The data shows that the relaxation process is (αβ) at low pressures, and resolves into components at high pressures. The behaviour of the (αβ) and resolved β relaxations is discussed, and mechanisms are proposed for these processes.
