Abstract
A thermosetting composition is provided which comprises the reaction product of (a) at least one N,N'-bis-imide of an unsaturated dicarboxylic acid, of general formula ##STR1## in which T represents a divalent organic radical containing a carbon-carbon double bond and Q is a divalent organic radical of 2 to 30 carbon atoms, (b) at least one polyamine of general formula EQU R (NH.sub.2).sub.x in which x is an integer at least equal to 2, and R represents an organic radical of valency x, the bis-imide being present in an amount of 0.55 to 25 mols per molar --NH.sub.2 group of the polyamine, and (c) at least one monomer other than a bis-imide of formula (I), which contains a carbon-carbon double bond and is heat-polymerizable.
