摘要：

The white noise spin-decoupled, natural abundance 13C nmr spectra of whole and fractionated poly(propylene oxide) have been obtained at 25.1 MHz. The spectra of the main-chain carbons are interpreted in terms of the structural and stereoregularities and defects in the chain backbone. The nmr analysis indicates that 89% of the crystalline fraction (mp 60°) and 49% of the noncrystalline fraction of this diethylzinc-catalyzed polymer consist of isotactic, structurally regular dyads. © 1969, American Chemical Society.
