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.
