Abstract : Studies of the poly(perfluoroalkylene-1,3,4-oxadiazole) systems have been continued using the following monomers: 1,3-bis(5-tetrazolys) perfluoropropane; 1,8-bis(5-tetrazolyl) perfluorooctane; bitetrazole; perfluorosebacoyl chloride; 5,5'-bis(n-perfluorobutyryl) chloride)-2,2'-bi-1,3,4-oxadiazole. Variations in reaction conditions and monomer ratios have been made. Limited effort has been devoted to other approaches for formation of the 1,3,4-oxadiazole rings; attempts were made to form a polymer incorporating 1,2,4-oxidiazole linkages. Syntheses have been carried out which gave new monomers containing triazole rings. (Author).
