Abstract
Polyether polyol comprising as alkylene oxide units ethylene oxide and propylene oxide units, said polyol having a nominal average hydroxyl functionality of 2-6, an hydroxyl value of 16-45 mg KOH/g, a primary hydroxyl content of at least 50% calculated on the total amount of hydroxyl groups and an amount of ethylene oxide units, calculated on the weight of the alkylene oxide units in the polyol, of 21-49% by weight these polyols are useful for making flexible foam.
