DEPT (Distortionless Enhancement by Polarization Transfer) spectra have been obtained on eight commercial polymers in order that the general applicability of this new multipulse technique for the assignment of carbon multiplicity in their proton noise decoupled 13C NMR spectra might be assessed. The spin-lattice and spin-spin relaxation times have been measured and correlated with the quality of the edited DEPT spectra.
