POLYETHER POLYOLS AND METHOD OF PREPARING SAME Abstract of the Disclosure New polyether polyols of predetermined structure are prepared by reacting polyether bis alcoholates with selected bis epoxides. Specifically, a polyoxyalkylene glycol is converted to the bis alcoholate, and then the bis alcoholate is reacted with an equivalent amount of a glycol bis glycidyl ether, with the reactants being mixed together all at once. The polyether polyalcoholate thus obtained is converted to a high molecular weight polyether polyol by acid neutralization or ion exchange. - 1 -
