Beschreibung
Zusammenfassung:	The invention relates to the use polymers obtained by polymerization of ethylenically unsaturated acids or anhydrides onto unsaturation-containing polyether polyols for producing polyol dispersions by acidolysis of polyurethane waste, as well as to the use of the resulting polyol dispersions for producing polyurethanes. L'invention concerne les polymères d'utilisation obtenus par polymérisation d'acides ou d'anhydrides à insaturation éthylénique sur des polyols de polyéther contenant une insaturation pour produire des dispersions de polyol par acidolyse de déchets de polyuréthane, ainsi que l'utilisation des dispersions de polyol obtenues pour produire des polyuréthanes.
