Abstract: Polyetherpolycarbonatediols are disclosed, which comprise (A) from 3 to 63.7 mol % of units derived from a polyoxytetramethylenediol; (B) from 63.7 to 3 mol % of units derived from a polyoxy-C2-C8-alkylenediol other than (A), an aliphatic alkanediol of from 2 to 14 carbon atoms, an alicyclic alkanediol of from 3 to 14 carbon atoms or an alkylene oxide of 2 or 3 carbon atoms, or a mixture thereof; and (C) from 33.3 to 50 mol % of units derived from phosgene, a dialkyl carbonate having C1-C4-alkyl groups or a cyclic carbonate having C2-C4-alkylene bridges, or a mixture thereof. These compounds are useful for producing thermoplastic polyurethanes, polyetheresters, polyetheramides, cellular polyurethane elastomers, casting elastomers and fibers.
