Beschreibung
Zusammenfassung:	The present invention relates to an unsaturated polyester polyol having at least 2 hydroxyl groups and a hydroxyl value of 11 to 225 mgKOH/g which is the reaction product of at least one dicarboxylic acid and at least one polyol, wherein at least one of the acid and polyol comprises dimer fatty acid and/or dimer fatty diol. The unsaturated polyester polyol is particularly suitable for reacting with polyisocyanates to form polyurethanes.
