one or more linear diols having a molecular weight of 62 g/mol to 500 g/mol, optionally in the presence of one or more catalysts, optionally in the presence of one or more additives, auxiliaries and/or additions, and optionally in the presence of one or more monofunctional chain terminators, characterized in that the reaction is effected in a solvent-free manner and comprises or consists of the following steps: 1) providing and reacting a mixture made up of the total amount of component, a portion of component and optionally a portion or the total amount of component, component and/or component, to give an NCO-functional prepolymer, where in process step 1) there is a molar ratio of component to component in the range from 1.1:1.0 to 5.0:1.0, 2) reacting the NCO-functional prepolymer from process step 1) with the total amount of component to obtain an OH-functional prepolymer, optionally in the presence of a further portion of component, component and/or component, 3) reacting the OH-functional prepolymer from process step 2) with the remaining amount of component and any remaining amount of component, component and/or component to obtain the thermoplastically processible polyurethane, where over all process steps there is a molar ratio of component to the sum total of component and component in the range from 0.9:1.0 to 1.2:1.0, where solvent-free means that the proportion of solvent is at most 1% by weight, based on the total weight of the reaction mixture, and a "solvent" is understood to mean a substance in which at least one of components A, B and C and, if present, D, E and/or F can be dissolved, dispersed, suspended or emulsified but which does not react with any of components A, B and C and, if present, D, E and/or F or with the polymer and the prepolymer(s). a) rollers and/or wheels, b) shoe soles, c) elastic bearing elements and/or elastic connection elements, preferably elastic bearing elements and/or elastic connection elements for automobiles, and d) components for the automobile interior, one or more essentially linear polyether polyols and/or polyester polyols, wherein the total amount of component has an average
