PROBLEM TO BE SOLVED: To provide a process that can conveniently produce a mixture of a propylene oxide adduct and an ethylene oxide adduct of a bis-phenolic compound in fewer steps.SOLUTION: Provided is a process for producing polyol mixture characterized in including a step for adding, in a solution in which a bis-phenolic compound (b2) is dissolved in a solvent containing a propylene oxide adduct (P) of a bis-phenolic compound (b1) and under a presence of catalyst, ethylene oxide to the bis-phenolic compound (b2) to produce an ethylene oxide adduct (E) of bis-phenolic compound (b2), in which, the average addition mole number m of propylene oxide in the propylene oxide adduct (P) is 1.0 to 30.0, and the average addition mole number of ethylene oxide in the ethylene oxide adduct (E) is 1.0 to 30.0.SELECTED DRAWING: None |
