Abstract
Disclosed are a polyol with a molecular weight distribution Mw/Mn of 4 or more, obtained by reacting a compound comprising an alkylene oxide compound (II) having a hydroxyl group in a base polyol (I) with a molecular weight of 2000 or more; and a polyol composition for a flexible polyurethane foam, comprising a polyol compound and a crosslinker, wherein the crosslinker comprises a polyol (a) with a hydroxyl value of 50 to 1100 mgKOH/g and with a primary hydroxylate ratio of 25% or more and 60% or less, which is obtained by an addition of a compound comprising alkylene oxide compound (ii) having a hydroxyl group to active hydrogen compound (i).
