The spherulitic crystallization of isotactic polypropylene from solution: On the evolution of monoclinic spherulites from dendritic chain-folded crystal precursors
Year: 1966
Type: article
Abstract: -crystallographic axis in intercrossing branches is circa 80°. The possible origin of this unusual mode of twinning, which involves an 80° change in the orientation of the chain axes in offspring branches from that in parent branches, is briefly presented. The process of evolution of monoclinic polypropylene spherulites from the unusually twinned dendritic crystal precursors is contrasted with the evolution of spherulites in other polymers; furthermore, the relevance of the observations presented in this study to an understanding of the origin of the previously reported atypical fine structures exhibited by monoclinic spherulites of polypropylene crystallized from the melt, is discussed.
