New imidyl-benzene-dicarboxylic and -tricarboxylic acid derivatives, in particular 5-maleimidyl-trimellitic acid derivatives and 3,5-bis-(maleimidyl)-phthalic acid derivatives, and a process for their manufacture are described. These imidyl-benzene-dicarboxylic and -tricarboxylic acid derivatives are suitable for the manufacture of crosslinkable polymers, above all polycondensation and polymerization products, which are distinguished by good processability and good solubility in customary organic solvents. Imidyl compounds, according to the definition, which have anhydride groups can also be used as curing agents for optionally modified epoxide resins.
描述了新的咪唑基苯二羧酸和三羧酸衍生物,特别是5-马来酰亚胺基三甲苯酸衍生物和3,5-双(马来酰亚胺基)邻苯二甲酸衍生物,以及它们的制备方法。这些咪唑基苯二羧酸和三羧酸衍生物适用于制造可交联聚合物,尤其是聚酯化和聚合产物,其特点是在通常的有机溶剂中具有良好的加工性和良好的溶解性。根据定义具有酐基的咪唑化合物也可以用作可选改性环氧树脂的固化剂。
