Most mixtures of high molecular weight polymers are not miscible in the absence of specific intermolecular interactions. We have used two dimensional NMR in solutions and in the solid state to probe these interactions and to gain a molecular level understanding of the forces that control polymer blend formation. The results show that weak, but specific intermolecular interactions often control the phase structure of polymer blends.
