✦ Synopsis
Atetraet--A procedure for determination of crystallinity in polymer blends is described. The procedure may be applied to two-component blends composed of a semicrystalline polymer and a completely amorphous one. The results for blends polypropylene/polystyrene and polyethylene/polystyrene are presented.

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
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
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
