FTIR
The structure of polymer was evaluated from the crystallinity point of view using XRD, FTIR, and DSC methods and from the surface properties using specific surface evaluation and porosity. 
DSC
Scanning electron microscopy was used to observe morphology of the surface and evaluate the particle size and shape via image analysis. 
Scanning electron microscopy
Results were confronted with laser diffraction particles size measurement along with an evaluation of the specific surface area.
