Abstract

Polymer-bound dyes have been prepared by the diazotization of high-polymeric [NP- (OC₆H₅)_x(OC₆H₄NH₂-p)_y]_n, followed by coupling to phenol, β-naphthol, 6'-NaO₃S-β-naphthol, and (paminophenyl) naphthalene. These reactions were preceded by model compound studies with the cyclic trimer [NP(OC₆H₄NH₂-p)₂]₃. In both cases, the aminophenoxy units were generated by reduction of 4-nitrophenoxy groups with PtO₂ and hydrogen. The phosphazene skeleton was unaffected by the reduction, diazotization, and diazo coupling processes. The physical characteristics of the trimers and high polymers are described.
