Computer method for the peak separation of data on X-ray crystalline diffraction and amorphous scattering of semicrystalline polymers at low angle range(20<50°)
is extended through wide angle range(20:5-140°) of X-ray diffraction-scattering by PET films. By comparing characteristic paramters of the separated most prominent amorphous peaks due to in-tersegmental scattering
the changes of the moTecular orientation at amorohous regions during PET film formation have been discussed.
