Popis:	Non-isothermal and isothermal thermomechanical analysis (TMA) of the cross-linking and hardening of wood joints bonded with urea-formaldehyde (UF), melamine-urea-formaldehyde (MUF), and phenol-melamine-urea-formaldehyde (PMUF) resins was carried out, allowing the determination of the variation of physical properties of these thermosetting adhesives in situ in the wood joint. Gelling temperature, hardening and vitrification temperature and temperature at which relative elastic moduli reach their maximum were also determined for wood joints obtained with the three resins. Deductions as regards rates of hardening, influence of amount of hardener and of curing temperature are reported on the basis of the measured TMA variation of the relative elastic moduli of the joints assemblies.
