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.
