BIOMASS-RESOURCE-DERIVED POLYURETHANE, METHOD FOR PRODUCING SAME, AND BIOMASS-RESOURCE-DERIVED POLYESTER POLYOL
摘要:
The invention relates to a method for producing a biomass-resource-derived polyurethane, which comprises: reacting a dicarboxylic acid and an aliphatic diol to produce a polyester polyol; and reacting the polyester polyol and a polyisocyanate compound, wherein the dicarboxylic acid contains at least one component derived from biomass resources, a content of an organic acid in the dicarboxylic acid is more than 0 ppm and not more than 1,000 ppm relative to the dicarboxylic acid, and a pKa value of the organic acid at 25° C. is not more than 3.7.
