ABSTRACT:
Crosslinkable mixtures of oligomers or polymers, containing terminal imidyl groups, and diamines are described, for example mixtures of a polyamide oligomer or polyamide-acid oligomer, or terminal polyamide polymer or polyamide-acid polymer, having maleimidylphthalic acid groups, and a diamine. These mixtures and the pre-polymers obtainable therefrom are soluble in customary organic solvents, and in general they can also be processed from the melt. The crosslinked products obtainable therefrom are distinguished in particular by their good thermo-oxidative stability.
