PROBLEM TO BE SOLVED: To provide a polyether polyol composition which exhibits excellent mechanical and physical properties when used as a polyurethane raw material, and to provide a preparation method of the polyether polyol composition.SOLUTION: A polyether polyol composition (S) contains a polyether polyol having 3-6 of the number of functional groups and a polyether diol or the polyether polyol having 3-6 of the number of functional groups, the polyether diol and an unsaturated polyether monool. The polyether polyol composition (S) has 10-100 mg-KOH/g hydroxyl value [X], 0-0.08 meq/g unsaturated polyether monool content [Y], 0.04-0.08 meq/g polyether diol content [Z], and 0-20 wt.% of the content [α] of an ethylene oxide unit per the weight thereof. X, Y, Z and α satisfy an inequality (1):(Y+Z)×(100-α)/100≤5.89×X. |
