TETRACARBOXYLIC ACID OR POLYESTERIMIDE THEREOF, AND PROCESS FOR PRODUCTION OF THE SAME

摘要

Disclosed is a useful, novel alicyclic polyesterimide. An alicyclic polyester imide which can be induced by reacting an alicyclic tetracarboxylic acid anhydrate having an ester group therein or a tetracarboxylic acid thereof (a starting material) with an amine to give an alicyclic polyesterimide precursor and imidating the alicyclic polyesterimide precursor. This alicyclic polyester imide is found to be a useful material in industrial fields.
