Beschreibung
Zusammenfassung:	A composition for polyurethane foams which comprises: one or more polyols and/or one or more polymer-containing polyols which are polyols containing, dispersed therein, fine polymer particles obtained by polymerizing a compound having an unsaturated bond; water; a catalyst; a foam stabilizer; and a polyisocyanate. The polyols comprise (A) a plant-derived polyol produced from a raw material obtained from a plant and (B) a low-monool-content polyol having a total degree of unsaturation of 0. 050 meq/g or lower. Also provided is a polyurethane foam obtained by foaming the composition for polyurethane foams. The polyurethane foam contributes to a reduction in environmental burden and gives a cushioning material having a well-balanced combination of moderate hardness, moderate resilience, and excellent durability.
