## Abstract Phenol‐urea‐formaldehyde (PUF) resins were synthesized by reacting mixture of methylolureas (MMU), phenol, and formaldehyde. The structure of PUF cocondensed resins at different stages of reaction were analyzed by liquid ^13^C nuclear magnetic resonance (NMR) spectroscopy. The liquid ^1

Both liquid-and solid-state 13 C-NMR spectroscopies were employed to investigate the cure-acceleration effects of three carbonates [propylene carbonate (PC), sodium carbonate (NC), and potassium carbonate (KC)] on liquid and cured phenolformaldehyde (PF) resins. The liquid-phase 13 C-NMR spectra sho
## Abstract A one‐ and two‐dimensional NMR study was performed on three commercial resol phenol—formaldehyde (PF) prepolymer resins. ^1^H, ^13^C, CSCM and DQF COSY NMR spectral data, in acetone‐__d__~6~, were obtained on each resin and on PF model compounds: phenol, five methylolphenols, four diphe
A series of phenol-formaldehyde resins was produced in the presence of NaOH catalyst. Detailed structural and quantitative information was provided by 13 C-NMR spectroscopy. The main interests were the relative quantities of bridge structures, methylol groups, and free phenol. Functionality and line
