Process for preparing aspartates |
摘要 |
The present invention relates to novel aspartates, their method of production and the use of these aspartates as reactive components for polyisocyanates in two-component polyurethane coating compositions and for preparing polyurethane prepolymers. The aspartates are prepared by first reacting a di- or polyamine with an unsaturated ester and then reacting the resultant product with a maleimide.
