Abstract
Procedure for the preparation of insoluble and infusible synthetic products, stable in storage and thermosetting, characterized by reacting with each other, at temperatures between 100 and 280ºC: a) N, N'-bis-imides of unsaturated dicarboxylic acids of the general formula **(See formula)** in which A stands for a divalent organic radical, with at least 2 carbon atoms and at most 30 carbon atoms, and B means a radical of the formulas **(See formula)** b) bis- (cyclopentadianyl) dimer or oligomer compounds of the general formula **(See formula)** in which X signifies a fluorine, chlorine or bromine atom; R1 and R2 each signify a hydrogen atom or a methyl group; n means an integer worth 1 at least and 4 at the most; and P stands for a number from 2 to 20, although optionally component b) can be replaced up to 50 mol% with bis- (cyclopentadienyl) compounds of formula III **(See formula)** in which And it means a radical of the formulas **(See formula)** or a divalent, aliphatic, cycloaliphatic, araliphatic or aromatic hydrocarbon radical, optionally in the presence of a hardening catalyst.
