CA 2384873
The invention relates to compounds with carbodiimide units and carboxyl or carboxylate groups (compound V) derived from a) aliphatic or araliphatic C4 to C20 polyisocyanates (component a), b) aminocarboxylic acids or aminocarboxylic acid salts (component b), c) optionally further compounds with groups capable of reacting with isocyanate groups in an addition reaction (component c) and d) optionally other isocyanates (component d), whereby the carbodiimide units are exclusively derived from the isocyanate groups of the components a).
L'invention concerne des carbodiimides comportant des groupes carboxyle et carboxylate (composés V), obtenus à partir a) de polyisocyanates C¿4?-C¿20? aliphatiques ou araliphatiques (composant a), b) d'acides aminocarboxyliques ou sels d'acides aminocarboxyliques (composant b) et c) éventuellement d'autres composés qui présentent des groupes pouvant réagir avec des groupes isocyanate au cours d'une réaction d'addition (composant c), d) éventuellement d'autres isocyanates (composant d), les motifs carbodiimides s'obtenant pratiquement exclusivement à partir des groupes isocyanate du composant (a).
