Claims
- 1. A process for producing elemental iodine and a copoly(arylene sulfide) corresponding to the structure:
- wherein A is a divalent substituted or unsubstituted aromatic radical, T is a monovalent aromatic radical, x is in the range of 0.5 to 0.001 and n is an integer from 1 to 100, said process consisting essentially of
- (1) reacting at a temperature above about 175.degree. C. a mixture of a diiodoaromatic compound which contributes the divalent radial A and a monoiodo aromatic compound which contributes the monovalent radical T and elemental sulfur to produce the elemental iodine and the copoly(arylene sulfide), and
- (2) recovering the elemental iodine.
- 2. The process of claim 1 wherein n is from 1 to 20.
- 3. The process of claim 1 wherein n is from 20 to 100.
- 4. The process of claim 1 wherein the aromatic radical is selected from the group consisting of phenylene, biphenylene, diphenyl ether, diphenyl sulfone, benzophenone, diphenoxybenzene and naphthalene.
- 5. The process of claim 4 wherein the aromatic radical is an unsubstituted phenylene or an unsubstituted biphenylene radical.
- 6. The process of claim 5 wherein the aromatic radical is unsubstituted phenylene.
- 7. The process of claim 1 wherein T is selected from the group consisting of ##STR6## where Y is selected from the group consisting of -NO.sub.2, -NH.sub.2, -OR, and -COOR where R is alkyl and from 1 to 4 carbons.
