ABSTRACT:
Aromatic bistriazene compounds of the formula ##STR1## wherein --R.sub.1, --R.sub.2, --R.sub.3, and --R.sub.4 are independently --H, --C.sub.6 H.sub.5, --C.sub.6 H.sub.4 Y, or C.sub.1 -C.sub.4 alkyl; --R.sub.5 -- is ##STR2## --R.sub.6 is --F, --Cl, --Br, --CH.sub.3, or --CF.sub.3 ; r is 0, 1, 2, 3, or 4; and --Y is halogen, --NO.sub.2, --C.sub.6 H.sub.5, or C.sub.1 -C.sub.4 alkyl. These bistriazene compounds are useful for cross-linking polymers such as poly(imides), poly(aryl ether ketones), poly(aryl ether sulfones), poly(quinolines), poly(quinoxalines), and nonaromatic fluoropolymers having aliphatic C--H groups.
