    Abstract: The invention relates to a method for modifying isocyanates, wherein at least one organic monomer isocyanate having an NCO functionality >1 is oligomerised in the presence of at least one catalyst, said method being characterised in that the catalyst comprises at least one specific compound having an NPN sequence selected from compounds of formula I (formula I), and/or from compounds of formula II (formula II) where HX represents an acid with a pKa value ≧2, X− represents the anion of an acid with a pKa value ≧2, and n represents an integer or fractional number between 0 and 20, wherein Y represents R12(R13)N— and/or one or more substituents of the structure of formula III (formula III) and wherein R1 to R19 independently represent identical or different substituents selected from C1-C20 alkyl-, C1-C20 cycloalkyl- and C6-C20 aryl groups, or wherein R1 and R2, R3 and R4, R5 and R6, R7 and R8, R9 and R10, R12 and R13, R14 and R15, R16 and R17, R18 and R19 independently represent identical or different substituents selected from C1-C20 alkylene-, C1-C20 cycloalkylene-, C6-C20 arylene groups, and can form a 3- to 12-membered ring with the N atom joined to the P atom. The invention also relates to the use of a catalyst of this type.
