K-17482/+ Substituted, unsaturated, bireactive bicyclic imides and the use thereof Abstract Imides of the formula I Image (I), in which R1, R2 and R4 independently of one another are hydrogen or methyl, R3 is a direct bond or a C2-C20aliphatic radical which can be interrupted by O atoms or a mononuclear or polynuclear C5-C20cycloaliphatic or C6-C20aromatic radical or is a group of the formula II Image (II), in which T is methylene, isopropylidene, CO, O, S or SO2 and R5 is hydrogen or phenyl, can be crosslinked either photochemically or by heat and produce polymers havingexcellent properties, in particular a very high resistance to heat. They are particularly suitable for the production of heat-resistant photolithographs or as matrix resins for the production of composite materials.
