摘要：
Solid-state nuclear magnetic resonance (NMR) studies of poly(ethylene oxide) conformations and packing was performed in a variety of environments and applied to PEO-poly(α-L-glutamate)(PGNa) blends. Results indicated that there was no significant crystalline complex with different PEO conformation or packing. Spin diffusion experiments indicated the proximity of amorphous PEO and PGNa on a 10 nm scale.
