## Abstract From a consideration of molecular dimensions and bond angles, it is deduced that a Novolak resin must consist of highly kinked, asymmetrical molecules. As a result, it is concluded that such a resin, when hardened with β€œhexa, β€œ will contain much less than the theoretically possible numb

## 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

The effects of temperature and relative humidity on phenol-formaldehyde resin bonding were evaluated. Two flakes in a lap-shear configuration were bonded under an environment of controlled temperature (110 ~ 120 ~ 130 ~ 140 ~ and relative humidity (41%, 75%, 90%) for a series of time periods (0.25 t
