    摘要: The present invention relates to a process for the production of polyisocyanates containing uretdione and/or isocyanurate groups bya) partially oligomerizing the isocyanate groups of organic diisocyanates to form uretdione and/or isocyanurate groups in the presence of catalysts containing trivalent phosphorus,b) terminating the oligomerization reaction at the desired degree of oligomerization by converting the catalyst into a catalytically inactive oxidized form by the addition of an oxidizing agent andc) subsequently removing unreacted diisocyanate by thin-layer distillation.The present invention also relates to the polyisocyanates containing uretdione and/or isocyanurate groups obtained by this process.Finally, the present invention also relates to the use of these polyisocyanates, optionally blocked with blocking agents for isocyanate groups, as the isocyanate component in polyurethane coating compositions.
