Abstract:
PROCESS OF PRODUCING ESTER RESIN CONTAINING ISOCYANURATE GROUPS AND IMIDE GROUPS IN THE POLYMER CHAIN COMPRISING CONDENSING A POLYALCOHOL WITH A TRICARBOXYLIC ACID OF THE FORMULA:
1,3,5-TRI(R-),2,4,6-TRI(O=)HEXAHYDRO-S-TRIAZINE
WHEREIN R REPRESENTS A MOIETY HAVING THE FORMULA:
(CH3-),(5-(HOOC-),1,3-DI(O=)-ISOINDOLIN-2-YL)PHENYL
CHARACTERIZED BY THE STEP OF FORMING SAID TRICARBOXYLIC ACID BY CONTACTING TRIPHENOLIC URETHANE TRIMERIZED TOLUYLENE DIISOCYANATE AND TRIMELLITIC ACID ANHYDRODE IN A MEDIUM CONTAINING THE POLYALCOHOL, AT A TEMPERATURE AND FOR A TIME SUFFICIENT FOR FORMATION OF SAID TRICARBOXLIC ACID.
