Abstract: Thermoplastic, elastic polyurethanes which are soluble in ethers and/or ketones and have a high surface hardness and high modulus of elasticity are manufactured from a polyester-ol and/or a polyether-ol, a substituted or unsubstituted diisocyanato-diohenylmethane or diisocyanato-diphenyl-sulfone, an aliphatic, branched-chain diol of the formula HOCH2-CR1R2-CO2OH, in which R1 is alkyl and R2 is alkyl or hydrogen, and, optionally, a triol.
