✦ Synopsis
AMtraet--The method of Hindeleh and Johnson and the method of Ruland and Vonk were employed for determination of the crystallinity in polyethylene, polypropylene and polyethyleneterephtalate. It was found that the values given by the methods are relatively close. However, using the method of Hindeleh and Johnson, the amorphous background approximation must be changed.

A new method for determining the crystallinity fraction of semi-crystalline polymers from X-ray powder diffraction measurements is presented. Using the scattering of an amorphous sample of the same material and a convenient expression for the disorder factor, the method can lead to precise separatio
