Process for continuous production of thermoplastic polyurethane by reaction of components one or more cycloaliphatic, aliphatic and/or araliphatic polyisocyanates, one or more cycloaliphatic, aliphatic and/or araliphatic polyols, wherein the total amount of component has a hydroxyl number of 600 mg KOH/g to 1830 mg KOH/g, determined in accordance with DIN EN ISO 4629-2:2016, optionally in the presence of one or more catalysts and/or one or more additives, characterized in that the process comprises the steps of: a) producing a mixture of a partial amount of component, a partial amount or the total amount of component and optionally a partial amount or the total amount of component, wherein a molar ratio of component to component in process step a) is in the range from 0.6: 1.0 to 0.95: 1.0; b) mixing the mixture produced in process step a) with a prepolymer output substream obtained from process step e); c) reacting the mixture from process step b); d) dividing the reaction mixture obtained in step c) into two output substreams; e) recycling an output substream from process step d) as an input substream for the mixture in process step b); f) mixing the remainder of component and optionally the remainder of components and with the remaining output substream of process step d); and g) reacting to completion the mixture obtained in process step f) to obtain a thermoplastic polyurethane. one or more cycloaliphatic, aliphatic and/or araliphatic polyisocyanates, one or more cycloaliphatic, aliphatic and/or araliphatic polyols, wherein the total amount of component has a hydroxyl number of 600 mg KOH/g to 1830 mg KOH/g, determined in accordance with DIN EN ISO 4629-2:2016, optionally in the presence of one or more catalysts and/or one or more additives, characterized in that the process comprises the steps of: a) producing a mixture of a partial amount of component, a partial amount or the total amount of component and optionally a partial amount or the total amount of component, wherein a molar ratio of component to component in process step a) is in the range from 0.6: 1.0 to 0.95: 1.0; b) mixing the mixture produced in process step a) with a prepolymer output substream obtained from process step e); c) reacting the mixture from process step b); d) dividing the reaction mixture obtained in step c) into two output substreams; e) recycling an output substream from process step d) as an input substream for the mixture in process step b); f) mixing the remainder of component and optionally the remainder of components and with the remaining output substream of process step d); and g) reacting to completion the mixture obtained in process step f) to obtain a thermoplastic polyurethane. a) producing a mixture of a partial amount of component, a partial amount or the total amount of component and optionally a partial amount or the total amount of component, wherein a molar ratio of component to component in process step a) is in the range from 0.6: 1.0 to 0.95: 1.0; b) mixing the mixture produced in process step a) with a prepolymer output substream obtained from process step e); c) reacting the mixture from process step b); d) dividing the reaction mixture obtained in step c) into two output substreams; e) recycling an output substream from process step d) as an input substream for the mixture in process step b); f) mixing the remainder of component and optionally the remainder of components and with the remaining output substream of process step d); and g) reacting to completion the mixture obtained in process step f) to obtain a thermoplastic polyurethane.
