POLYOL FOR POLYURETHANE PREPARATION AND POLYURETHANE PREPARATION METHOD USING SAME |
摘要 |
In order to provide a polyol that resolves such issues as insufficient mechanical properties and moisture resistance in urethane elastomers and polyurethane foams produced using prior polyols, a polyol (PL) for polyurethane preparation is disclosed that comprises the following polyol (a) and the following strength-enhancing agent (b). Polyol (a): a polyoxyalkylene polyol that is the alkylene oxide adduct of an active hydrogen-containing compound (H), in which at least 40% of a hydroxyl group positioned on the terminal is a primary hydroxyl group-containing group represented by general formula (I). [In general formula (I), R1 represents a hydrogen atom or a C1-12 alkyl group, cycloalkyl group, or phenyl group.] Strength-enhancing agent (b): a compound that is at least one compound selected from the group comprising an ester compound, a thioester compound, a phosphoric acid ester compound, and an amide compound, and that is derived from a polyvalent aromatic carboxylic acid with a valence of 2 or higher. |
