The effect of spherulitic truncation on small-angle light scattering
Authors:R. J. Tabar  R. S. Stein  D. E. Rose
Abstract:The effects of spherulitic truncation on the Hv small-angle light-scattering (SALS) patterns are determined by computer simulation of spherulite nucleation and growth. The simulation is carried out for simultaneous and sporadic nucleation of two-dimensional spherulites and simultaneous nucleation of three-dimensional spherulites. The scattered intensity differences between truncated spherulites and round spherulites are determined as functions of the type of growth and the volume (or area) fraction of spherulites. Methods for the determination of certain geometrical characteristics of spherulites systems by SALS are developed. These characteristics include the volume (or area). fraction of spherulites, the average spherulite radius, and the average spherulite volume (or area). The results of this study are essential in the quantitative analysis of Hv SALS from spherulitic systems. The simulation process is readily extendable to the examination of other morphological phenomena by SALS.
