Bromine (BRP) or chlorine modified Phenolic resins (CLP) were prepared by the reaction of paraharogenated phenol-phenol mixtures with formaldehyde. Boron modified Phenolic resins (PBP) were prepared by the esterification of boric acid with phenol, followed by the polycondensation with paraformaldehyde.<br>The flame retardance of the modified resins was evaluated in comparison with the unmodified resin (GP) by the measurement of oxygen index, and found to be in the order: BRP>PBP>CLP> GP.<br>The higher was the heat-treatment temperature, the higher was the heat distortion temperature (HDT) of resin. The HDT of resin was in the order: PBP, GP>BRP>CLP. This order was the same as the results of flexual properties.<br>The resistance against thermooxidative degradation of the resins was examined by means of thermogravimetry and differential thermal analysis, and the higher resistance was observed by the order of PBP>GP≈CLP>>BRP.
