Abstract Sixteen polymers containing thiazole and aromatic rings in the polymer chain were prepared and investigated for the production of fibers and films that would be useful up to about 500°C. None of these polymers was completely satisfactory. Some of the polymers gave tough fibers and films, but they had relatively low melting points (<300°C). Other polymers did not melt below 500°C, but they did not have good fiber and film forming properties because of their low molecular weights. Fibers and films of one of the polymers (polytetramethylenephenylenethiazole) were prepared, and their physical properties, hydrolytic stabilites under acid and alkaline conditions, and resistence to ultraviolet and gamma radiations were determined.
