More Information
Summary:The polycarbonate diol of the present invention comprises terminal hydroxyl groups and repeating units represented by the following formula (A), and in the measurement of 1H-NMR using deuterated chloroform as a solvent and tetramethyl silane as a reference material, the integral value of 3.33 ~ 3.43 ppm is 0.1 to 10.0 when the integral value of the signal of 3.90 ~ 4.45ppm being set to 1000. In formula (A), R represents a divalent aliphatic or alicyclic hydrocarbon having 3 to 15 carbon atoms, one, two or more may be selected from the repeating units.
