Epoxidized natural rubber — Determination of epoxidation and ring opening level by NMR spectrometry

Caoutchouc naturel époxydé — Détermination de l'époxydation et du niveau d'ouverture des anneaux par spectrométrie RMN

Abstract / scope

This document specifies a quantitative method, using proton (1H) nuclear magnetic resonance (NMR) spectrometry, for the determination of epoxidation and ring opening level of raw epoxidized natural rubber (ENR). This method applies to ENR of all grades available commercially.
