摘要:
Thermostable heterocyclic polymers containing phenyl-substituted quinoxaline and both amide and imide units have been synthesized by low-temperature solution polycondensation of diaminophenyl-quinoxalines with diacid chlorides of certain aromatic acids containing preformed imide rings. Also, copolymers have been obtained in which a mixture of diaminophenylquinoxaline and diaminooxadi-azole or diaminobenzimidazole was used in the reaction with the same diacid chlorides. The thermal stability and the electrical insulating properties of these products are discussed and compared with related heterocyclic polymers.
