POLYIMIDE PRECURSOR AND RESIN COMPOSITION CONTAINING SAME

摘要

A polyimide precursor characterized by having a structure derived from 2,2'-bis(trifluoromethyl)benzidine (TFMB) or the like as a diamine-derived structure and also having both a structure derived from a specific alicyclic tetracarboxylic acid dianhydride and a structure derived from an aromatic tetracarboxylic acid dianhydride as structures each derived from a tetracarboxylic acid dianhydride, wherein the degree of imidation of an amide bond derived from the alicyclic tetracarboxylic acid dianhydride is 10 to 100%.
