| titleOfInvention |
Stable aromatic amine composition, a process for preparing color stable aromatic amines, and the production of light colored aromatic amine-based polyether polyols |
| abstract |
This invention relates to stable aromatic amine compositions. These compositions comprise a) an organic compound containing at least one carboxylic acid group, and b) an aromatic amine. This invention also relates to a process for stabilizing the color of aromatic amines, and to the use of these aromatic amines as initiators for the preparation of polyether polyols. |
