| Reactant | Phenol | HCID 996 | — |
| Reactant | Thiophosphoryl chloride | HCID 19883 | — |
| Product | Phenylthionophosphonic dichloride | HCID 19016 | — |
Reaction Steps
Phenol is treated with an excess of thiophosphoryl chloride (at reflux) to yield phenyl thiophosphoryl dichloride ##STR16## and this product was condensed with p-nitroaniline and hydrogenated as set out in Example 1. The corresponding polymer is obtained by polycondensation with isophthaloyl chloride as in Example 2. The inherent viscosity was 0.9 dl/g.
