## 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
