The experimental time of 13 C-NMR quantitative analysis of phenol-formaldehyde resins was reduced so that quantitativeness was maintained. The quantitative spectra of 14 model resins were obtained using a gated decoupling technique suppressing the NOE. The paramagnetic additive, Cr(acac) 3 , was use

The diazonium salts of aniline and 4,4ะˆ-diaminodiphenylmethane coupled with phenol and resorcinol were condensed with formaldehyde in alkaline media to yield polymeric resins. These polymers were found to readily react with metal ions like Cu 2ฯฉ and UO 2 2ฯฉ , forming polychelates. The azodyes, resin
