Abstract:
A process for oligomerizing isocyanates includes a step of continuous conversion of an isocyanate monomer into polyisocyanate containing carbamate and/or allophanate groups, in the presence of a catalyst, wherein the conversion step is carried out in a reactor having a specific heat exchange coefficient of greater than or equal to approximately 200 kW/m3/° C.
