METHOD FOR PRODUCING AMIDES OR POLYAMIDES BY USING AROMATIC CARBAMATES BY WAY OF ISOCYANATES AS PRECURSORS THROUGH CATALYZED THERMAL PROCESSES AND METHOD FOR PRODUCING AROMATIC CARBAMATE PRECURSORS FROM AROMATIC AMINES

The present invention is directed to a process for preparing amides or polyamides by replacing isocyanate starting materials of a catalyzed thermal reaction with aromatic carbamates. Through the catalyzed thermal process involving a non-isocyanate precursor of the present invention, efficiency for producing amides or polyamides can be significantly improved, and the impure side products produced from a side reaction of isocyanate can be greatly curtailed. Hence, amides or polyamides of high purity and yield can be achieved. The invention also relates to a process for preparing aromatic carbamates, the new non-isocyanate precursors for amides or polyamides.
