    • The present invention relates to a process for preparing pure bis(isocyanatoalkyl)monouretdiones corresponding to formula (I) ##STR1## wherein R represents identical or different, linear or branched alkyl groups having 4 to 9 carbon atoms, by oligomerizing at least a portion of the isocyanate groups of aliphatic diisocyanates in the presence of catalysts which accelerate the dimerization of isocyanate groups, terminating the reaction at the desired degree of oligomerization, removing unreacted excess diisocyanate by extraction or thin film distillation to obtain a distillation residue, subjecting the distillation residue to thin film distillation at a temperature of 160.degree. to 220.degree. C. and a pressure of 0.01 to 1.0 mbar and obtaining bis(isocyanato-alkyl)monouretdiones corresponding to formula (I) as the distillate. The present invention also relates to the resulting bis(isocyanato-alkyl)monouretdiones corresponding to formula I and to their use for the production of polyisocyanate addition products, in particular as the isocyanate components in polyurethane coatings compositions, in which the isocyanate groups may optionally be present in blocked form.
