Conclusions
Polyanthanthroylenebenzimidazole has been prepared by a two-stage method. Some principles have been studied, and optimum conditions have been established for the first stage of the synthesis — preparation of the prepolymer.
The possibility of cyclizing the prepolymer to polyanthanthroylenebenzimidazole has been demonstrated.
Model yarn specimens have been prepared and a preliminary evaluation of their properties has been given.
