| titleOfInvention | Tetracarboxylic dianhydrides and precursors and their production |
| abstract | PROBLEM TO BE SOLVED: To provide a tetracarboxylic dianhydride which is useful as a raw material of a polyimide and a precursor thereof, a curing agent for an epoxy resin, etc., and is excellent in hydrolysis resistance, flexibility and flexibility. And a method for producing the same. SOLUTION: A method for producing a tetracarboxylic dianhydride represented by the following general formula (1), wherein a specific tetracarboxylic acid and a derivative thereof, a specific tetranitrile, and a specific tetracarboxylic acid are dehydrated and ring-closed. . (Wherein, R represents a hydrogen atom, a halogen atom, a carbon number of 1 to 10) A plurality of Rs may be the same or different from each other, and X represents a divalent organic group containing a carbon-carbon unsaturated bond or an aromatic ring; Is 0 or 1, and k, m and n are each independently 1 to 10 Is an integer of |
