摘要 |
The present invention relates to a process for preparing oligocarbonate polyols having a number average molecular weight of 500 to 5000 g/mol by reacting organic carbonates and aliphatic polyols in the presence of a metal acetylacetonate catalyst based on a metal which has an atomic number in the PTE of 39, 57, 5 9 to 69 or 71. The present invention also relates to the oligocarbonate polyols obtained by this process.
