Abstract:
A process for the preparation of a polyether polyol comprising catalytic reaction of an H-functional initiator with a lower alkylene oxide in the presence of a catalyst, wherein the catalyst comprises a multimetal cyanide compound and the H-functional initiator comprises a mixture of butane-1,4diol and another H-functional initiator, a mixture of &agr;-hydroxy-&ohgr;-hydroxypoly(oxybutane-1,4-diyl) and another H-functional initiator, a mixture of pentane-1,5-diol and another H-functional initiator, a mixture of decane-1,10-diol and another H-functional initiator, a mixture of butane1,4-diol, of &agr;-hydroxy-&ohgr;-hydroxypoly(oxybutane-1,4-diyl), pentane-1,5-diol, and/or decane-1,10-diol and another H-functional initiator, wherein said another H-functional initiator is glycerol and/or trimethylol propane.
