| Abstract: | A chemical determination of methylol group in active phenol-formaldehyde (PF) resins was introduced. Methylol contents in PF resins were determined by 13C NMR and the chemical analysis method respectively. The method was verified to be feasible by comparing analytical results with known formulations. |
