In Details , Using a Dielectric spectroscopy experiment on the Polypropylene glycol polymer to get the following:

1- the relaxation time of the alpha and beta relaxations of the above polymer dependence of the storage and loss moduli of the polymer.

2- In details, state the experimental steps equations, relations and figures to get the relation time and the activation energy.

3- sketch the the dielectric spectra of Polypropylene glycol shown that alpha and beta relaxations peaks in terms of glass transition.

when using a broad frequency and measuring its response.
