Poly-Schiff base containing bisthiazole rings (TAPDA) has been prepared from terephthalaldehyde and 2,2 -diamino-4,4-bisthiazole. It was found that the TAPDA polymer film is permeable to H 2 , O 2 , and N 2 and can be converted into an electrical conductor by pyrolysis at high temperature in nitroge
Ten new polyesterazomethines have been synthesized by solution polycondensation of five different diamines with 4,4'-[terephthaloyloxy]bis-3-ethoxybenzaldehyde and 4,4'-[isophthaloyloxy]bis-3-ethoxybenzaldehyde using dimethylacetamide in the presence of anhydrous LiCL. Fibrous polymers were precipit
