ABSTRACT:
Polymer-bound dyes have been prepared by the diazotization of high polymeric [NP(OC.sub.6 H.sub.5).sub.x - (OC.sub.6 H.sub.4 NH.sub.2 -p).sub.y ]n, followed by coupling to phenol, .beta.-naphthol, 6'-NaO.sub.3 S-.beta.-naphthol, and p-aminophenylnaphthalene. These reactions were preceded by model compound studies with the cyclic trimer [NP(OC.sub.6 H.sub.4 NH.sub.2 -p-).sub.2 ].sub.3. In both cases, the aminophenoxy units were generated by reduction of 4-nitrophenoxy groups with the use of PtO.sub.2 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.
