Description / Abstract: 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.
