Abstract

Process for obtaining polyisocyanate-based foamed materials, using fatty acid ester and mono- and/or polyisocyanate reaction products, characterized in that as fatty acid esters, those containing at least one fatty acid incorporated are used aliphatic with more than 8 carbon atoms in the molecule, acidity indexes between 0 and 100, OH indexes between 0 and 150, with at least one of the two measurement figures having a value greater than 0 and possessing average molecular weights between 500 and 5000.
