Title (EN) PROCESS FOR MAKING POLYETHERS WITH REDUCED AMOUNTS OF UNSATURATED MONOLS
(FR) PROCÉDÉS DE PRÉPARATION DE POLYÉTHERS À TENEURS RÉDUITES EN MONOLS INSATURÉS
Abstract:
(EN) Unsaturated polyether monols are removed from polyether polyols by reaction with a functionalized thiol compound or a polythiol compound. This process replaces the terminal unsaturation with a functional group, or else couples two or more of the monols to form a polyol. The functionality of the polyether polyol product is increased by the removal of the monols.
(FR) Les monols de polyéther insaturés sont retirés des polyols de polyéther par réaction avec un composé thiol fonctionnalisé ou un composé polythiol. Ce procédé remplace l'insaturation terminale par un groupe fonctionnel, ou bien couple deux des monols ou davantage pour former un polyol. La fonctionnalité du produit de polyol de polyéther est augmentée par le retrait des monols.
