Abstract
Bis(benzilyloxy) compounds having the general formula ##STR1## wherein Ph is --C.sub.6 H.sub.5 and Ar is Ph, --C.sub.6 H.sub.4 Br, --C.sub.6 H.sub.4 CH.sub.3 or --C.sub.6 H.sub.4 C.sub.2 H.sub.5. These compounds can be reacted with bis(o-diamines) to form polyquinoxalines which can be converted to thermally stable compositions by non-volatile, intramolecular cyclization.
