Process for the preparation of bismaleimides |
| abstract |
A novel process is described for the preparation of bismaleimides of the formula n<IMAGE>n in which, in the first step, maleic anhydride, of the formula n<IMAGE>n is converted with a methylbisaniline of the formula n<IMAGE>n in an unhalogenated aromatic hydrocarbon as solvent to give the corresponding amide acid, and this amide acid is converted, without isolation, in the second step in the presence of an acidic catalyst to give the end product of formula I. |
