ABSTRACT
The properties of liquid and cured PF resin modified with alcohols were investigated in the study. The following alcohols were used in the study: ethanol, butanol, 1,2-ethanediol, 1,3-propanediol, 1,4-butanediol, 1,2,3-propanetriol. It was found that the modification of phenolic resin with the applied alcohols does not deteriorate its pot life at the temperature of 20°C, and in case of polyalcohols it caused an increase in its reactivity at higher temperatures, expressed by the shortening of gelation time at 130°C and the lowering of activation energy of resin gelation. The results of FTIR tests of polycondensed modified PF resins indicate that polyalcohols not only catalyze the polycondensation reaction of the PF resin, but also are built into its structure.
Key words: PF resin, polyalcohols.
