The blending of two immiscible polymer samples can lead to spherical inclusions of one component in a matrix of the other component. The mechanical solid‐state properties as well as the flow behavior of the m+lt depend on the size of the spheres in the blend. For that reason, the sphere‐size distribution is of major interest. Information about this distribution is often obtained by analyzing thin slices of the blend with transmission electron microscopy. In that way, however, the sphere‐size distribution itself is not obtained. The reconstruction of the sphere‐size distribution is introduced as a stereological problem, well known in fields as metallurgy, biology, geology, and medicine. It is shown that the sphere‐size distribution can be reconstructed using a regularization method as implemented in the program FTIKREG. © 1994 John Wiley & Sons, Inc.
