Polishing pad |
| abstract |
The purpose of the present invention is to provide: a polishing pad which is not susceptible to deterioration due to moisture absorption in a moisture-absorbing environment, while having excellent polishing characteristics, service life characteristics and high polishing rate; and a method for producing the polishing pad. A polishing pad of the present invention has a polishing layer that is formed of a polyurethane foam having fine cells. The polyurethane foam is a reaction cured body of a chain extender and an isocyanate-terminated prepolymer which is obtained by reacting a prepolymer starting material composition that contains an isocyanate component, a high molecular weight polyol and an aliphatic diol. The high molecular weight polyol contains a polyalkylene glycol A that has a peak of the molecular weight distribution within the range of 200-300 and a polyalkylene glycol B that has a peak of the molecular weight distribution within the range of 800-1,200. |
