    WHEREIN R IS HYDROGEN, ARYL, CARBONYL, AMINO, DIARYL AMINO OR A HETEROCYCLIC GROUP AND R'' IS AN AROMATIC GROUP, ARE PREPARED BY REACTING AN AROMATIC DIAMINE WITH A S-TRAZINE DIANHYDRIDE. THESE POLYIMIDES CAN BE FABRICATED INTO FILMS, COATINGS, LAMINATES AND THE LIKE. THE POLYIMIDES ARE ALSO FUSIBLE AND MOLDINGS THUS OBTAINED ARE LOW IN VOID CONTENT.

    摘要: 4,6-bis(alkaryl)-s-triazines having the structure

    WHEREIN R is hydrogen, alkyl, aryl, amino, carboxyl, nitrogen heterocyclic or a diarylamino group, and Y is an alkyl substituted aromatic group, can be prepared by a Freidel-Crafts reaction from cyanuric chloride and an alkyl substituted aromatic compound. These compounds are useful in preparing s-triazine anhydrides which in turn are useful in preparing high temperature polyimide polymers.

    摘要: WHEREIN R is hydrogen, alkyl, aryl, amino, carboxyl, nitrogen heterocyclic or a diarylamino group, can be prepared by reacting a dihalo triazine such as 2-phenyl-4,6-dichloro-striazine with o-xylene and thereafter oxidizing the intermediate to yield the above acid. By dehydrating the acid a corresponding dianhydride is obtained. Such compounds are useful in preparing various polymers, as for example polyimides.
