Product 1

HCID 19016Phenylthionophosphonic dichloride

Procedure

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.
