Polymer-dispersed polyol and method for manufacturing a soft polyurethane foam

Provided is a polymer-dispersed polyol that is made from starting materials derived from natural oils/fats and realizes a decrease in viscosity without a decrease in biomass percentage or a loss in the performance of a soft polyurethane foam obtained from said polymer-dispersed polyol. Also provided...

Beschreibung
Zusammenfassung:	Provided is a polymer-dispersed polyol that is made from starting materials derived from natural oils/fats and realizes a decrease in viscosity without a decrease in biomass percentage or a loss in the performance of a soft polyurethane foam obtained from said polymer-dispersed polyol. Also provided is a method for manufacturing a soft polyurethane foam using the provided polymer-dispersed polyol. The polymer-dispersed polyol is characterized in that polymer microparticles are dispersed in a matrix that includes: a polyol (a1) derived from natural fats/oils; and an epoxidated natural fat/oil (x). In the provided method for manufacturing a soft polyurethane foam, a polyisocyanate compound and a polyol containing the provided polymer-dispersed polyol are reacted in the presence of a catalyst and a foaming agent.
