| titleOfInvention |
Nonporous molded article for polishing layer, polishing pad, and polishing method |
| abstract |
As a non-porous molded article of a thermoplastic polyurethane, the thermoplastic polyurethane is a non-porous molded article for an abrasive layer having a maximum loss tangent (tan δ) in the range of -70 to -50 °C of 4.00 x 10 -2 or less. Preferably, the thermoplastic polyurethane is obtained by polymerizing a high molecular weight diol having a number average molecular weight of 650 to 1400, an organic diisocyanate, and a chain extender, and the nitrogen content rate derived from the isocyanate group of the organic diisocyanate is 5.7 to 6.5 mass%. . |
