摘要： A mixture comprises a polycarbonate polyol with a decomposition temperature of ≥ 180 °C at ≥ 0.1 mbar to ≤ 1 mbar which is based on at least two different diols selected from the group consisting of C 4 , C 5 and C 6 diols, the mixture having an altogether low amount of amines and/or ammonium ions, alkali metal atoms and/or ions, earth alkali metal atoms and/or ions, metals and/or ions of the 13th through 15 th Group of the Periodic Table of the Elements (i.e. metals from Boron, Carbon and Nitrogen Group), and transition metal atoms and/or ions of the 4 th through 12 th Group of the Periodic Table of the Elements in relation to the total weight of the polycarbonate polyol. Furthermore, the pH value of the 10 weight-% slurry of this mixture in water lies in the range from ≥ 5.0 to ≤ 8.0. The present invention also relates to the use of these polyols for the production of polyurethanes, in particular dispersions and thermoplastic polymers.
