| titleOfInvention | Polycarbonate diol having excellent thermal stability and method for producing the same |
| abstract | An object of the present invention is to provide a polycarbonate diol having good transparency with little change in molecular weight and composition without deterioration of the color tone of the polycarbonate diol even when heated. A polycarbonate diol having a number average molecular weight of 250 or more and 5500 or less and containing at least a structural unit derived from a dihydroxy compound having a site represented by the following general formula (1) in a part of the structure, An acid and / or phosphorous acid is further contained, and the total content of phosphoric acid and phosphorous acid is 0.1 mol times or more with respect to the total content of metal elements derived from the transesterification catalyst in terms of phosphorus atoms. A polycarbonate diol characterized by having a molar ratio or less. [Selection figure] None |
