摘要：

Magic-angle cross-polarization 13C-NMR spectra have been obtained of the prepolymeric, cured, and postcured versions of an acetylene-terminated polyimide resin. Analysis of the differences between the spectra establishes that all acetylenic functionality is lost by prolonged curing and that not more than 30% of the acetylenic end groups undergo cyclotrimerization in the cross-linking process. © 1979, American Chemical Society.
