Zusammenfassung:	Use of compounds selected from polyols derived from dimer fatty acids and /or dimer fatty alcohols as toughening agent in a process for making polyisocyanate polyaddition reaction products, in particular for polyisocyanate polyaddition reaction products having a hardblock > 40 % and a process for making said products. L'invention concerne l'utilisation de composés choisis parmi des polyols dérivés d'acides gras dimères et/ou d'alcools gras dimères en tant qu'agent durcisseur dans un procédé de fabrication de produits de réaction de polyaddition de polyisocyanate, en particulier pour des produits de réaction de polyaddition de polyisocyanate présentant une séquence dure > 40 % et un procédé de fabrication desdits produits.
