| Abstract: | A polyether polyols with low monol and high reactivity were prepared by steps of:(a) using a double metal cyanide catalyst (DMC) to prepare polyoxypropylene polyols with low unsaturation and high molecular weight;(b) treating said polyol with alkali compound;(c) capping said base treated polyol with ethylene oxide.The hydroxyl value of the obtained polyether glycols and triols is about 26 mgKOH/g,The unsaturation of the polyols is about 0.007 mmol/g,and the molar fraction of primary hydroxyl groups is over 85%. |

| Keywords: | polyether polyol low unsaturation high molecular weight high reactivity polyther polyurethane |
