The unsaturation of a hydroxyl-containing compound can be reduced by reaction with a nitrile oxide compound such as tetramethyl terephthalonitrile, N,N'- dioxide. The reaction of a nitrile oxide with terminal unsaturation associated with the preparation of a polyol from propylene oxide reduces the monol content of the polyol composition.

L'insaturation d'un composé contenant un hydroxyle peut être réduite par réaction avec un composé d'oxyde de nitrile tel que le tétraméthyl téréphtalonitrile, N,N'-dioxyde. La réaction d'un oxyde de nitrile à insaturation terminale associée à la préparation d'un polyol issu d'un oxyde de propylène réduit la teneur en monols de la composition polyol.
