Abstract : The polyheterocycles with perfluoromethylene bridges in the basic chain which are described in the literature are either cross-linked (structured polyperfluoromethylene triazines) or low-molecular linear polymers (polyperfluoromethylene benzoxazoles, polyperfluoromethylene benzimidazoles, etc.) For the first time high-molecular linear polyheterocycles were obtained with perfluoromethylene bridges: (Poly(bibenzoxazolediyl-phenylene-hexafluorotrimethylene-phenylene) and poly(bibenzimidazolediyl-phenylene-hexafluorotrimethylene-phenylene). These were synthesized from derivatives of alpha, omega-(di-(4'-carboxyphenyl)) perfluoropentane. (Author)
