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.
具有一般式##STR1##的双苄氧化物,其中Ph为--C.sub.6 H.sub.5,Ar为Ph,--C.sub.6 H.sub.4 Br,--C.sub.6 H.sub.4 CH.sub.3或--C.sub.6 H.sub.4 C.sub.2 H.sub.5。这些化合物可以与双(o-二胺)反应形成聚喹噁啉,通过非挥发性的分子内环化可以将其转化为热稳定的组合物。
