✦ Synopsis

Abstract

Four ethylene‐1‐hexene copolymer samples were studied by small‐angle X‐ray scattering in order to investigate the correlation between the crystalline lamellar thickness and the comonomer content. The lamellar thickness was determined from the identity period of the one‐dimensional scattering function and from the analysis of the one‐dimensional correlation function. The crystallinity and the volume of the crystalline unit cell were determined by wide‐angle X‐ray scattering. Some considerations are reported on the effect of the side chains during the crystallization and on the polydispersity of the lamellar thickness.
