Poly (thio-1, 4-phenylene)[poly (p-phenylene sulfide)] is a useful high-performance polymer because of its high temperature resistance, dimensional stability, solvent resistance, and high conductivity. 1 In this connection, there have also appeared a large number of patents and papers on syntheses, chemical properties, and industrial use of oligo (thio-1, 4- phenylenes). On the other hand, although thiophene has played a very important role in ...
