Method for producing light-coloured polyisocyanates |
| abstract |
The invention relates to a method for producing light-coloured polyisocyanates by phosgenation of mixtures containing MDA and multinuclear aromatic polyamines that have omicron-phenylenediamine units incorporated via methylene bridges. The invention further relates to polyisocyanate mixtures obtainable by this method. |
