The sequence distribution of ethylene-vinyl acetate copolymers has been studied using 13C nmr spectroscopy. Signal attributions were obtained both by following the rules of Grant and Paul as well as by comparison of spectra of samples of varying composition. Quantitative analysis at low vinyl acetate content are reported. Zerothorder Markoffian distribution of the monomer units in the copolymer chain was verified. In addition, a 13C spectrum of solid polymer was obtained.

Abstract
The sequence distribution of ethylene-vinyl acetate copolymers has been studied using 13C nmr spectroscopy. Signal attributions were obtained both by following the rules of Grant and Paul as well as by comparison of spectra of samples of varying composition. Quantitative analysis at low vinyl acetate content are reported. Zerothorder Markoffian distribution of the monomer units in the copolymer chain was verified. In addition, a 13C spectrum of solid polymer was obtained.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
