Summary:PURPOSE:To obtain a process of producing a polyol for a hard polyurethane foam improved in compression strength and made less brittle. CONSTITUTION:There is provided a process of producing an aromatic amine type polyether polyol that is obtained by condensation reaction between 0.1 to 0.9mol aldehyde and 1mol alkylene oxide adduct obtained by addition reaction of 1mol aromatic amine with 2 to 50mol alkylene oxide.
