Abstract:Resorcinol (R) and formaldehyde (F) gel synthesis has been well-studied along with alternative reagents. We present the synthesis of formaldehyde-based xerogels using chemically similar s-triazine precursors, with comparison to traditional analogues. The substitution ranges from tri-hydroxyl to tri-amine, with an intermediate species, allowing changing chemistry to be investigated. Each molecule (X) offers different acid/base properties, known to influence gel formation, as well as differences in crosslinking … Show more
“…Xerogels are gels that retain their porous structure after drying at ambient condition. In this regard, Prostredny et al [1] investigate the impact of replacing resorcinol in resorcinol-formaldehyde gels with s-triazine precursors on the crosslinking and texture of the resulting xerogels. The substitution of the z-triazine precursor ranging from tri-hydroxyl to tri-amine allows changing the chemistry and acid-base properties of the gelation reaction.…”
