Abstract

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.
