In Details , Using a dynamic mechanical analysis (DMA) 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 and the equations to get the relation time and the activation energy.

when using a sinusoidal deformation at a fixed frequency and measuring its response.
