DISPERSANT FOR PRODUCING POLYOL DISPERSIONS FROM POLYURETHANE WASTE
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 pro...
