✦ Synopsis


The structure of chlorinated natural rubber (CR) was studied by infrared and NMR spectroscopy. It was shown that the structure proposed by Troussier (these de Docteur-Ingenieur, Lyons, 1954) does not fit the W-NMR characteristics of this compound. CR was fractionated and each fraction was characterized. The thermal stability of CR and the evolution of its structure in various experimental conditions was studied by NMR.
