ABSTRACT:
Crosslinkable mixtures of bis-imidyl derivatives and diamines are described, for example of the bis-imide of 2 moles of 3-maleimidyl-phthalic acid anhydride and one mole of 4,4'-diaminodiphenylmethane and a diamine. These mixtures are characterized by their good solubility in a large number of organic solvents, and they can also be processed from the melt. The crosslinked products obtainable therefrom are distinguished in particular by their good thermooxidative stability.
