摘要：

Xe-128 NMR spectroscopy is employed to demonstrate that polyepichlorohydrin and poly(vinylmethylether), which have virtually equal glass transition temperatures, form thermodynamically miscible blends. This conclusion is drawn from the appearance of a single resonance in the blend spectrum, at a chemical shift differing from that calculated for the fast exchange regime. C-13 NMR results are consistent with thermodynamic miscibility, and reflect the similarity of the component dynamics.
