Abstract
A method of producing a polyether compound containing a hydroxyl group according to the present invention includes polymerizing an AO in an AO-containing raw material with an initiator containing a hydroxyl group in a presence of a composite metal cyanide complex catalyst, in which a content of methanol in the AO-containing raw material is 0.0001 ppm or greater and less than 20 ppm with respect to a total mass of the AO-containing raw material, a method of producing a polyether compound containing a reactive silicon group further includes converting a hydroxyl group of a polyether compound into a group containing a reactive silicon group, a method of producing a polyether compound having a urethane bond further includes reacting a polyether compound containing a hydroxyl group with a polyisocyanate, and a method of producing a polyether compound containing a polymerizable unsaturated group further includes converting a hydroxyl group of a polyether compound into a group containing a polymerizable unsaturated group.
