Abstract
Poly(1,3,4‐oxadiazole‐2,5‐diylvinylene) and poly(1,4‐phenylene‐1,3,4‐oxadiazole‐2,5‐diylvinylene) were prepared by polymerizing different quantities of terephthalic acid (T), maleic acid (M), and hydrazine sulfate (HS) in the presence of fuming sulfuric acid. Homopolymers of M and T and various copolymers of M:T were prepared. The polymers were characterized by viscosity, IR, UV, and elemental analysis. Their solubility in different solvents was investigated. The relative thermal stability of the polymers was evaluated by TGA and DTA.Keywords
