ABSTRACT:
This invention is a process for the preparation of a polyol having an equivalent weight of 200 to 5000 by the reaction of a monoepoxy compound with an initiator containing an active hydrogen atom in the presence of a catalyst substance selected from the group consisting of barium, strontium and their oxides, hydroxides, hydrated hydroxides or monohydroxide salts, and mixtures thereof. The process comprises adding water during the reaction of the monoepoxy compound with the initiator. The quantity of water added is one percent or less by weight of the total weight of monoepoxy compound to be reacted with the initiator.
