In Details , Using a Dielectric spectroscopy experiment on the Polypropylene glycol polymer with molecular weight 400 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- in Details, state All experimental data obtained from the experiments.

4- How analyze the experimental data obtained at different temperatures to obtain the activation energy and pre-exponential factor of the relaxation process.

3- insert a typical plot of the dielectric constant versus frequency to show the alpha and beta relaxations peaks in terms of glass transition.
