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.
