More Information
Summary:The invention relates to dispersants obtained by polymerization of ethylenically unsaturated acids or anhydrides onto mercapto-functionalized polyether polyols, to their use 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 des dispersants obtenus par polymérisation d'acides ou d'anhydrides à insaturation éthylénique sur des polyols de polyéther à fonction mercapto, leur utilisation 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.
