  • Carbodiimides with carboxyl or carboxylate groups
    Patent number: 7049001
    Abstract: Compounds with carbodiimide units and carboxyl or carboxylate groups (compounds V), derived from a) aliphatic or araliphatic C4 to C20 polyisocyanates (component a) b) hydroxy carboxylic acids or hydroxy carboxylic salts (component b) and c) if desired, further compounds, carrying groups able to react with isocyanate groups in an addition reaction (component c) d) if desired, other isocyanates (component d), the carbodiimide units being derived essentially exclusively from the isocyanate groups of component a).
