METHOD TO IMPROVE THE RIGIDITY OF POLY-ISOCYANATE POLYADITION REACTION PRODUCTS, AND, PRODUCTS UNDERSTANDING POLY-ISOCYANURATE, POLYURETHANE AND / OR POLYURETHIA Use of compounds selected from polyols derived from dimer fatty acids and / or dimer fatty alcohols, such as stiffening agent in a process for the manufacture of polyisocyanate polyaddition reaction products, in particular for polyisocyanate polyaddition reaction products having hard blocks> 40% and a process for manufacturing said products. |
