Abstract: Mechanical and electrical properties have been investigated as a useful tool for the relaxation phenomena study of polymeric materials through the complex elastic modulus E* and the complex relative permittivity Ɛ* analysis[1], under isothermal and isochronal conditions obtained by dynamic techniques. The experimental results provide a basis to establish a correlation between the electrical and mechanical characteristics of the material[2]. Classical rheological models based on traditional calculus are inaccurate while describing the physical phenomena associated with some molecular motions that the material presents due to segments rearrangement in the polymer chains. Thus, the application of differential and integral operators of non-integer order, known as fractional calculus, as an alternative for the properties description in polymer systems and its validation with experimental results is suggested[3,4].
