PROCESS FOR PREPARING MONO AND POLYASPARTATES |
摘要 |
The present invention relates to a new process for preparing mono and polyaspartates from primary mono and polyamines and maleates in presence of five-membered aromatic ring compounds containing nitrogen atoms in the ring structure as catalysts and use of these mono and polyaspartates as reactive components for polyisocyanates in two-component polyurethane coating compositions and for preparing polyurethane prepolymers.
