Beschreibung
Zusammenfassung:	A liquid polyethercarbonatediol compound, useful for producing a thermoplastic polyurethane having excellent weathering resistance, softness and stretchability, comprises a reaction product of (1) a carbonate-ester compound with (2) a polyetherdiol compound having, in the molecular structure thereof, structural units of -RO-(a) and structural units of -(CH 2 )-O-(b) and/or -CH 2 CH(CH 3 )-O-(c), in which reaction product, average molecular numbers n and m of the structural units (b) and (c), per mole of the structural units (a) satisfy the requirements: 0 ¤ n ¤ 5 , 0 ¤ m ¤ 5 and 1 < ( n + m ) ¤ 5.
