New poly(propylene-ran-1-butene) copolymers were analyzed to study the influence of different processing techniques on their structure and morphology. Wide-angle X-ray diffraction allowed determination of the percentage of the γ form and the crystallinity in the samples and also the influence of the percentage of 1-butene on the cell parameters. Furthermore, it was possible to appraise the contributions of different stacks of lamellae to the small-angle X-ray diffraction patterns.

Abstract
New poly(propylene-ran-1-butene) copolymers were analyzed to study the influence of different processing techniques on their structure and morphology. Wide-angle X-ray diffraction allowed determination of the percentage of the γ form and the crystallinity in the samples and also the influence of the percentage of 1-butene on the cell parameters. Furthermore, it was possible to appraise the contributions of different stacks of lamellae to the small-angle X-ray diffraction patterns.
