ABSTRACT:
A polyether polyol composition, the reactivity of which with a polyisocyanate can be controlled, to thereby obtain an isocyanate group-terminated prepolymer having excellent storage stability. A polyether polyol composition comprising a polyether polyol obtained by a ring-opening polymerization of an alkylene oxide in the presence of a composite metal cyanide complex catalyst, and a phosphoric acid compound comprising a phosphoric acid selected from orthophosphoric acid, polyphosphoric acid and polymetaphosphoric acid, and/ or a partial ester of such a phosphoric acid, wherein the polyether polyol composition contains metals derived from the composite metal cyanide complex catalyst in an amount of from 1 to 30 ppm based on the polyether polyol, and the above phosphoric acid compound in an amount of from 0.5 to 100 ppm based on the polyether polyol.
