    摘要： The present invention relates to a polyol composition comprising anhydrosugar alcohols and an anhydrosugar alcohol polymer and, more specifically, to a polyol composition comprising a monoanhydrosugar alcohol, a dianhydrosugar alcohol, and a polymer of a monoanhydrosugar alcohol and/or a dianhydrosugar alcohol, the polyol composition being usable in various fields since the physical property conditions of the composition, such as number average molecular weight (Mn), polydispersity index (PDI) and hydroxyl value, satisfy specific levels, and, particularly, being capable of remarkably improving the physical properties of a polyurethane, such as tensile strength and elongation, when used as a polyurethane chain extender.

    摘要： The present invention relates to a solid dispersion, a preparation method therefor, a chain-extended polyurethane using same, and an epoxy resin composition comprising same and, more particularly, to a solid dispersion in which an inorganic or organic material-derived isotropic or anisotropic substance is used as a dispersoid and dispersed at room temperature in a solid-phase dispersion medium such as polyols and sugars, whereby the dispersion can be easily stored and used, reduce transportation cost, prevent or alleviate the aggregation or precipitation caused during the storage of products, with the results of working efficiency improvement and processing cost reduction, and, when applied to polyurethane, can increase strength and provide an improved strength, compared to conventional curing agent, a preparation method therefor, a chain-extended polyurethane using same, and an epoxy resin composition comprising same.

    摘要： The present invention pertains to: a polyol composition containing a polysaccharide alcohol, a polysaccharide alcohol-derived anhydrosugar alcohol, and an anhydrosugar alcohol polymer; and a polyurethane foam including same. More specifically, the present invention pertains to: a polyol composition containing a) a monoanhydrosugar alcohol, b) a dianhydrosugar alcohol, c) a polysaccharide alcohol, d) a polysaccharide alcohol-derived anhydrosugar alcohol, and e) at least one polymer of a) to d), wherein physical properties such as the number average molecular weight (Mn), polydispersity index (PDI), and average number of OH groups per molecule of the polyol composition satisfy certain levels, the polyol composition can contribute to the improvement of physical properties such as strength, elongation, and thermal insulation when used as a raw material for polyurethane, etc., using a hydrogenated sugar composition obtained from a saccharide mixture containing glucose and polysaccharides (disaccharides or higher saccharides) improves productivity, and costs can be reduced compared to the case of using conventional high-purity hydrogenated sugar; and a polyurethane foam including same.
