A polyimide composition is obtained by adding triallyl isocyanurates to polyimide, preferably with further addition of an accelerator and diluting solvent. The composition is made to show effective reduction in dielectric constant as well as in the inherent viscosity and surface tension so that, when employed in manufacturing laminates, the degree of impregnation into base material can be elevated to remarkably improve resin filling.

Une composition de polyimide est obtenue par addition d'isocyanurates de triallyle à un polyimide, préférablement avec addition ultérieure d'un accélérateur et d'un solvant diluant. La composition ainsi préparée présente une réduction efficace de la constante diélectrique, ainsi que de la viscosité inhérente et de la tension superficielle, ce qui permet, lorsqu'on l'utilise pour la fabrication de laminés, d'augmenter le degré d'imprégnation dans le matériau de base et d'améliorer ainsi remarquablement le remplissage de résine.
