Beschreibung
Zusammenfassung:	A polycarbonate diol composition contains: a polycarbonate diol containing a structural unit (1) derived from a compound (1) represented by the following general formula (1); and an aldehyde having 3 or more and 8 or less carbon atoms. A method for producing a polycarbonate diol composition, includes: polycondensing a carbonate compound and a dihydroxy compound composition containing a compound (1) represented by the following general formula (1) and an aldehyde having 3 or more and 8 or less carbon atoms by a transesterification reaction in the presence of a catalyst, to obtain a polycarbonate diol composition containing a polycarbonate diol. A polyurethane is obtained by using this polycarbonate diol composition. HO-(CH2)n-OH (1)(In the general formula (1), n is an integer of 3 to 6.)
