Polyisocyanates containing isocyanurate groups and a process for their production |
| abstract |
The present invention relates to a process for the production of an isocyanurate group-containing polyisocyanate by a) partially reacting the isocyanate groups of an organic diisocyanate containing aliphatically and/or cycloaliphatically bound isocyanate groups in the presence of an ammonium or phosphonium fluoride trimerization catalyst, b) introducing carbon dioxide into the reaction mixture at least periodically during the reaction and c) terminating the reaction at the desired degree of conversion. The present invention also relates to the isocyanurate group-containing polyisocyanates obtained in accordance with this process. |
