    Abstract: A polyester-polyol being liquid at 40° C. and having a viscosity of not more than 10,000 mPa.s at 60° C., prepared by polycondensation of an acid component including at least one phthalic acid component selected from phthalic anhydride and o-phthalic acid, and an aliphatic polybasic acid, with a polyhydric alcohol; a process for preparing a polyurethane foam including reacting a polyisocyanate component with a polyol component including the polyester-polyol; a process for preparing an isocyanate prepolymer from a polyisocyanate component and a polyol component including the polyester-polyol; and a process for preparing a polyurethane foam including reacting an isocyanate prepolymer prepared from a polyisocyanate component and a polyol component including the polyester-polyol, with a polyol component. The resulting polyurethane foam shows remarkably improved physical properties such as tensile strength and tear strength, while having low density, acceptable appearance and texture.

    Abstract: A process for producing a polyurethane foam which comprises mixing a polyol solution comprising 100 parts by weight of a polyester-polyol, 0.1 to 1.8 parts by weight of water and 0.1 to 5 parts by weight of urea, and a catalyst with a polyisocyanate compound and foaming the mixture. According to the process, there can be produced a polyurethane foam which satisfies both productivity and moldability even when having a low density, and is suitable for use in shoe soles.
