ABSTRACT:
New crosslinkable tetra-imidyl derivatives are described which are obtained by reaction of 3,5-bis-imidylphthalic acid derivatives, e.g. 3,5-bis-maleimidyl-phthalic acid anhydride, with monomeric, oligomeric or polymeric diamines. The new crosslinkable tetra-imidyl derivatives are suitable for the production of various shaped articles, such as coating compositions and mouldings, and are distinguished by their good crosslinking properties.
