Abstract: A process for producing elemental iodine and a copoly(arylene sulfide) corresponding to the structure ##STR1## wherein y is in the range of 0.001 to 0.15, x is in the range of 0.02 to 0.65 and n is at least 100, consisting essentially of (1) reacting at a temperature above about 175.degree. C., a mixture of diiodobenzene and diiodobiphenyl and elemental sulfur to produce the copoly(arylene sulfide), and (2) recovering the elemental iodine.
