    Abstract: A resin composition containing: an ester compound including a carboxylic acid ester obtained by using (1) a monohydric alcohol having an alkyl group having 1 to 4 carbon atoms; (2) a dicarboxylic acid having an alkylene group having 2 to 4 carbon atoms; and (3) a dihydric alcohol having an alkylene group having 2 to 6 carbon atoms, the ester compound having an acid value of 1.00 mgKOH/g or less, a hydroxyl value of 5.0 mgKOH/g or less, and a number-average molecular weight of from 300 to 700; and an aliphatic polyester. Since the resin composition of the present invention inhibits the generation of volatile compounds, the resin composition can be suitably used in various industrial applications, such as daily sundries, household electric appliance parts, and automobile parts.

    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.
