Beschreibung
Zusammenfassung:	Melamine-polyol dispersions comprising ethoxylated alcohols of specific structures are disclosed. Such dispersions maintain their stability under stationary conditions for at least 24 hours and are useful in the manufacturing of polyurethane foams. The resulted polyurethane foams display more evenly-distributed flame retardant properties. L'invention concerne des dispersions mélamine-polyol comprenant des alcools éthoxylés de structures spécifiques. De telles dispersions maintiennent leur stabilité en conditions stationnaires pendant au moins 24 heures et sont utiles pour la fabrication de mousses de polyuréthane. Les mousses de polyuréthane résultantes présentent des propriétés ignifuges distribuées de manière plus homogène.
