Abstrakt: Analysis of the 220-MHz proton NMR spectra of several kinds of poly(propylene oxide-a-d) samples prepared with anionic, cationic and coordinate catalysts provided additional and confirming evidence for the previous analysis by 100-MHz proton NMR spectral studies. The spectra are exactly analyzed in terms of dyads for absorptions arising from methylene protons in the main chain of the polymer.
