    Abstract: The present invention relates to a process for the production of polyisocyanates containing uretdione groups bya) oligomerizing a portion of the isocyanate groups of diisocyanates having aliphatically and/or cycloaliphatically bound isocyanate groups in the presence of catalysts or catalyst systems which accelerate the dimerization of isocyanate groups and in the presence of trisubstituted phosphite stabilizers corresponding to formula (I) ##STR1## b) optionally termination of the oligomerization reaction at a degree of oligomerization of 10 to 60% by adding a catalyst poison andc) optionally removing unreacted diisocyanate by extraction or thin-layer distillation.The present invention also relates to the use of the resulting uretdione polyisocyanates as a starting component for polyurethane plastics, particularly as an isocyanate component for the production of uretdione hardeners for powder coating compositions.
