Methods for preparing esters and amides of trimellitic anhydride and products therefrom |
| abstract |
ESTERS OR AMIDES OF TRIMELLITC ANHYDRIDE CAN BE PREPARED BY REACTING THE LATTER DIRECTLY WITH EITHER A POLYOL OR A DISECONDARY AMINE AT ELEVATED TEMPERATURES AND BY A REARRANGEMENT REACTION INVOLVING THE ELIMINATION OF WATER TO OBTAIN THE ESTER OR AMIDE POLYANHYDRIDE. POLYAMIDE ACID RESINS AND POLYIMIDES CAN BE PREPARED FROM SUCH COMPOSITIONS. |
