The effect of hydrostatic pressure up to 1,361 atms on the dielectric properties of a segmented polyurethane elastomer (Dow 2103-80AE) is studied at temperatures from 0Β°C to 80Β°C. The experimental results show that the relaxation time for both the I-process, associated with the molecular motions in
