✦ Synopsis

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 separation of the crystalline and amorphous contributions by a fitting procedure. In this way, the crystallinity fraction and the disorder factor are automatically obtained. The method is applied to polyethylene terephthalate.

Abstmet A new method of additions is described for x-ray diffraction determination of trace crystalline silica. The method is derived from Klug and Alexander, X-ray Diffraction Procedures (Wiley, 1974, p. 536, Bqn. 7-14) and is expressed as x = sR,(l -R,)/(R, -Rx) where x and s are the concentration

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 Hindele
