Abstract
Provided is a polyol composition which has good dispersion stability of a polyuria resin contained therein and maintains a uniform appearance over time as well as during the production, and which can be reacted with polyisocyanate to obtain a polyurethane foam having excellent flame retardancy. The present invention pertains to a polyol composition that is used as a raw material for a polyurethane foam containing a urea group-containing reaction product having a compound (A), which has two primary amino groups and at least one polyalkyleneoxy chain (a) in the molecule, and a polyisocyanate (B) as essential raw materials, and being obtained by reacting the primary amino groups of the (A) with the isocyanate groups of the (B), wherein the polyalkyleneoxy chain (a) is a chain to which 1-100 moles of a C2-4 alkylene oxide have been added.
