New heat-stable polymers containing imide groups. These polymers are obtained by reaction, at a temperature ranging from 50 DEG C to 300 DEG C, between: (a) one or more N,N'-bismaleimides, (b) one or more acrylic diesters of dihydroxylated, optionally di(polyoxyethylated) aromatic compounds, and (c) an imidazole compound. These polymers are employed for the production of moulded articles, laminates and articles with a cellular structure. |
