Polyols having reduced terminal unsaturation and a process for producing same |
摘要 |
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.
