✦ Synopsis

The charging and discharging currents were investigated in a synthetic melanin sample. The presence of long-lasting dielectric relaxation was established. The steady state was reached after a long time, from lo3 to lo5 s, which depends both on temperature and voltage.

The temperature dependence of polarization was of an activation character (En = 0.67 eV). The kind of electrode material did not influence the current curves.

A study of the dielectric relaxation spectrum of poly (monocyclohexyl itaconate) (PMCHI) is performed by means of two experimental techniques: first, at variable frequency in the audio zone and, second, by thermally stimulated depolarization currents. Because of the high conductivity of the samples,

Dielectric relaxation measurements were carried out on eight chlorinated polyethylene-polypropylene (PEPP) copolymers in the range of temperatures covering the main dielectric absorption. Chlorination of PEPP is expected to change the dynamic dielectric properties gradually with increasing amount of
