Thermocuring and heat resistance of the complexes of sodium borate with phenol-formaldehyde resol resin were studied by thermal analysis and infrared spectroscopy. The results showed that the curing process is an exothermal reaction. On heating, condensation reaction of the hydroxymethyl groups in the complexes takes place and forms methylenes or carbonyl groups. With increase of sodium borate in the complexes the heat resistance of the complexes increases significantly.
