ResumoA method has been devised for the measurement of crystallinity in oriented polypropylene fibres by an X-ray technique. The general level of crystallinity is higher than in similar oriented poly(ethylene terephthalate) fibres. The results also show that the crystallinity so measured is lower than values inferred from density measurements and that no correlation exists between the two methods. A possible method is suggested for the determination of the atactic content of polypropylene polymer by X-ray diffraction.
