Organic chemistry
Since the invention of the first synthetic polymer product, bakelite, synthetic polymer products have frequently been invented.
Polythiazyl
Polythiazyl (polymeric sulfur nitride), (SN), is an electrically conductive, gold- or bronze-colored polymer with metallic luster. It was the first conductive inorganic polymer discovered and was also found to be a superconductor at very low temperatures (below 0.26 K). It is a fibrous solid, described as "lustrous golden on the faces and dark blue-black", depending on the orientation of the sample. It is air stable and insoluble in all solvents.
