摘要:
AbstractA theory is presented to account for the effect of the impingement of growing spherulites on theirHvsmall‐angle light scattering patterns. The theory is developed on the basis of results of computer‐simulated two‐dimensional spherulite growth and calculated scattered intensities. The impingement produces a lowering of the intensity of the scattering maximum and the diminishing of the overall sharpness of the scattering peak. The extent of these effects increases with area fraction of spherulites. A procedure is suggested for determining correction factors that may be applied to intensity data obtained during the course of spherulite crystallization. An interpretation is made of the type of average spherulite size determined from the scattering angle of maximum inte
