Cycloaliphatic diisocyanates optionally in the form of isomer mixtures and a process for their production |
| 摘要 |
Diisocyanates and isomer mixtures of diisocyanates corresponding to the formula <IMAGE> in which R1, R2, m and n are as defined herein are produced by phosgenating diamines and isomer mixtures of diamines corresponding to the formula <IMAGE> in which R1, R2, m and n are as defined herein. These diisocyanates which are liquid at room temperature and highly compatible with polyols are particularly useful in the production of polyurethanes.
