Abstract
A low dielectric polyimide composition comprises an aliphatic anhydride, a long chain diamine, and an ester diamine. A polyimide made of such low dielectric polyimide composition has low polarizability group, thus the dielectric constant of the polyimide is lower. A polyimide made of the low dielectric polyimide composition, a polyimide film using the polyimide, and a copper clad laminate using the polyimide film are also provided.
