## 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
## Abstract The varying polymer structures of wood adhesive‐type urea–formaldehyde resins resulting from different formaldehyde/first urea (F/U~1~) mole ratios used in the first step of resin manufacture were investigated using ^13^C. As the F/U~1~ mole ratio decreased progressively from 2.40 to 2.
A particleboard adhesive-type urea-formaldehyde (UF) resin was made at a formaldehyde ratio of 2.10 and added with a second urea at low temperature to the typical final formaldehyde/urea ratio of 1.15. Time samples taken during heat treatments of the resin sample up to 70°C over a period of 250 min
