<p>3-11942 Heat-curable mixtures which are based on polyimides and poly-.beta.-iminocrotononitriles and are stable on storage and their use Heat-curable mixtures which are stable on storage and consist of a) poly-imides of specific unsaturated dicarboxylic acids of the general formula I in which A is a x-valent organic radical having at least 2 and not more than 30 carbon atoms, Z is a radical of the formulae and x is the number 2 or 3, and b) poly-(.beta.-iminocrotono-nitriles) of the formula II, III and/or IV in which Y is a m-valent organic radical having at least 2 and at most 30 carbon atoms, R' is a hydrogen atom or an alkyl having 1 to 6 carbon atoms, cycloalkyl having 5 or 6 carbon atoms or aryl having 6 to 10 carbon atoms, R is an aliphatic or aromatic radical having not more than 30 carbon atoms, E, together with the two nitrogen atoms, is a five-membered or six-membered ring, m is 2 or 3 and n is 1 or 2, are suitable for the production of moulded materials, preferably by casting the resin mixture or by laminating or bonding substrates.</p> |
