Patent

CA 2396945

The invention relates to compounds with carbodiimide units and carboxyl or carboxylate groups (compounds V), which are derived from a) aliphatic or araliphatic C4 to C20 polyisocyanates (component a) b) hydroxycarboxylic acids or hydroxycarboxylic acid salts (component b), c) optionally additional compounds which bear groups and which can react with isocyanate groups in an addition reaction (component c) and d) optionally other isocyanates (component d). In the main, the carbodiimide units are derived exclusively from the isocyanate groups of component (a).

Composés à motifs diimide et groupes carboxyle ou carboxylate (composés V) dérivés de a) polyisocyanates aliphatiques ou araliphatiques en C¿4?- à C¿20? (composants a) ; b) acides hydroxycarboxyliques ou sels d'acides hydroxycarboxyliques (composants b) et, c) éventuellement, d'autres composés porteurs de groupes capables de réagir avec des groupes isocyanate dans une réaction d'addition (composants c) ; d) éventuellement, d'autres isocyanates (composants d), les motifs carbodiimide dérivant essentiellement exclusivement des groupes isocyanate des composants (a).
