摘要：

The miscibility of two high‐performance polymers, an aromatic poly(ether‐imide) and a poly(aryl‐ether‐ketone), was investigated by a novel combination of solid‐state NMR techniques. This involves a new type of selection of 1H magnetization based on chemical shift differences, 1H spin diffusion during the mixing time and high‐resolution 13C detection. Mixing of components on a molecular scale is proved directly. Copyright © 1990 John Wiley & Sons, Ltd.
