| titleOfInvention | Thermoplastic polyurethane |
| abstract | PROBLEM TO BE SOLVED: To provide a thermoplastic polyurethane excellent in heat resistance, hot water resistance and elastic recovery property. SOLUTION: A polyester polyol (A-1) having a number average molecular weight of 1000 to 5000 having a crystallization enthalpy of 70 J / g or less and a polyether polyol (A-2) having a number average molecular weight of 500 to 2500. A polyol composition in which the blending ratio of A-1) and polyether polyol (A-2) is 80 mol% or more, and the polyol composition has a hydroxyl group average functional group number (f) of 2.006 to 2.100. (A); organic diisocyanate (B); and chain extender (C): 1.00 ≦ b / (a + c) ≦ 1.10. (Wherein, a represents the total number of moles of polyol in the polyol composition (A), b represents the number of moles of the organic diisocyanate (B), and c represents the number of moles of the chain extender (C).) This is solved by a thermoplastic polyurethane obtained by reacting at a ratio satisfying the above. [Selection figure] None |
