Process for the preparation of uretdione group containing polyisocyanates |
| abstract |
The present invention relates to a process for the preparation of uretdione group containing polyisocyanates comprising reacting monomeric aromatic diisocyanates in the presence of 1,2-dimethylimidazole used as a catalyst in an inert organic solvent whereby the weight ratio of solvent to diisocyanate lies in a range of from 0.1:1 to 2:1. |
