Abstract Three‐dimensional (3D) image patterns of phase‐separated poly(methyl methacrylate) (PMMA)/poly(styrene‐ ran ‐4‐bromostyrene) (PS‐Br) blends heated at 180°C for 6, 8, and 10 h were observed by 3D NMR microscopy with 3D X‐ray microscopy in order to characterize the 3D structure of the polymer blends using a standard 3D reconstruction protocol program for obtaining the 3D digital array of the PS‐Br/PMMA morphologies. The phase‐separated structure of the polymer blends in several 10‐μm scales was reasonably characterized. The phase‐separated structure of polymer blends by 3D NMR images was quantitatively consistent with that by 3D X‐ray images. It can be said that 3D NMR microscopy is a very useful means for analyzing the 3D structure of phase‐separated polymer blends as well as 3D X‐ray images. © 2006 Wiley Periodicals, Inc.
