Abstract

FIELD: synthesis of organic compounds. SUBSTANCE: reaction of synthesis of imide-containing prepolymer is carried out by reaction of carboxylic acid anhydride with di- or polyisocyanate in the presence of copper oxide, aluminium oxide, silicon oxide used as catalysts. EFFECT: improved method of synthesis. 3 tbl
