Abstract
The present invention relates to a process for the preparation of polyisocyanates by oligomerizing isocyanates corresponding to formula I (OCN-CH2)X (I) wherein X represents the residue obtained by removing the OCN-CH2 group from a monomeric polyisocyanate, wherein the residue contains 3 to 20 carbon atoms and at least one NCO group, in the presence of hydrogen-polyfluoride oligomerization catalysts corresponding to formula II Mn+ n[F-((HF)m] (II) wherein M represents an n-valent cation and m is >= 0.1. The present invention is also directed to the polyisocyanates obtained by this process.
