ABSTRACT: Glass forming materials are characterized by a complex relaxation pattern, which evolves over several time decades. Dielectric spectroscopy has proven particularly useful for studying such scenario as it is able to monitor the dielectric dynamics of a system over a range up to 16 time decades. In this work we study effect of thermodynamic history on activation volume of secondary relaxation inside the glassy forming systems, Poly[(phenyl glycidyl ether)-co-formaldehyde], (PPGE) and 1,18-bis (p methoxyphenyl) cyclohexane (BMPC), with two different type of secondary relaxation. Our results show that at bout systems, activation volume of secondary depends to the thermodynamic history.
