Abstract
New imidyl-benzenedicarboxylic acid derivatives, in particular 5-maleimidyl-isophthalic acid derivatives and 5-(nadic acid-imidyl)-isophthalic acid derivatives, and a process for their manufacture are described. These imidyl-benzenedicarboxylic 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 the customary organic solvents.
