POLYCYCLIC DIAMINES AND METHOD OF PREPARATION |
| 摘要 |
Polycyclic diamines, incorporating a basic framework similar to [3.3.3]propellane, and derivatives of the basic polycyclic diamines and a process for preparing same are provided. The diamines are prepared by subjecting bispyridine compounds to electroreductive coupling in an acidic solution. The polycyclic diamines and derivatives thereof are useful as chain extenders, crosslinking agents and curatives in various polymer systems.
