NOVEL DIAMINE, NOVEL ACID DIANHYDRIDE, AND NOVEL POLYIMIDE COMPOSITION FORMED THEREFROM

摘要

A diamine, an acid dianhydride, and a polyimide composition comprising monomer units derived from these, which each has photoreactivity and thermal reactivity. The diamine and the acid dianhydride are synthesized so as to have a photoreactive and thermally reactive group having one or more double or triple bonds, especially a skeleton of cinnamic acid, chalcone, benzalacetophenone, stilbene, coumarin, pyrone, allyl, propargyl, acetylene, or derivatives of these, and to combine the photoreactivity with the thermal reactivity characteristic of these reactive groups. The polyimide composition is formed from the diamine and the acid dianhydride.
