Abstract
The disclosure describes a cyclohexane-1,2,4,5-diimide derivative which can be used for the production of colorless transparent polymer and novel engineering plastics having good processability and solubility with an excellent physical property, and a process for preparing the same which comprises reacting a bicyclooctene-1,2,4,5-tetracarboxylic anhydride with alkylamine and aniline derivative and then oxidizing the resulting product with ozone, potassium permanganate, ruthenium chloride hydroxide and aqeous hydrogen peroxide under non-basic condition to convert double bond to dicarboxylic acid or dialdehyde without destroying the imide group.
