Plastics — Polyols for use in the production of polyurethanes — Determination of degree of unsaturation for polyols by Raman spectrometric method

Plastiques — Polyols destinés à la production de polyuréthanes — Détermination du degré d'insaturation des polyols par spectrométrie Raman

Abstract / scope

This document specifies a method to measure the total unsaturation of polyether polyols used in the production of polyurethanes by a Raman spectrometric method. It is not applicable to unsaturated compounds that are conjugated with a carbonyl group, a carboxyl group, or a nitrile group.
