1,3,5-Triglyceratetriazine [first tier (G(1))] and tri(1,3,5-triglycerate) triazine [second tier (G(2))] dendrimers were prepared with 1,3,5-trichlorotriazine and sodium glycerate in a 1 : 3 mass ratio in an ethanolic medium. G(1) and G(2) were amorphous, white, solid substances. Their structures were elucidated with IR, H-1-NMR, and C-13-NMR, and their thermal stability was studied with thermogravimetric analysis. The activation energy was calculated with the Freeman-Carroll model. Densities, viscosities, and surface tensions for 0.01-0.08 mol/kg aqueous solutions increased at 0.01 mol/kg for sodium glycerate, 1,3,5-trichlorotriazine, 1,3,5-triazine triglycerate chloride, G(1), and G(2). These values were measured at 298.15 K. The apparent molal volume, reduced viscosity, and inherent viscosity were calculated from the densities and viscosities, respectively. The data were regressed for the limiting densities, limiting apparent molal volumes, intrinsic viscosities, limiting inherent viscosities, and limiting surface tensions for solute-solvent interactions. The positive limiting apparent molal volume values were noted in the order of G(2) > 1,3,5-triazine triglycerate chloride > G(1) > 1,3,5-trichlorotriazine > sodium glycerate, with weaker hydrophilic intermolecular interactions of G(2). The higher intrinsic viscosity and limiting inherent viscosity values for G(2) implied stronger G(2)-H2O hydrophilic interactions, and the higher limiting apparent molal volume of G(2) indicated slightly higher dynamic conformational changes in comparison with G(1), with stronger structural activities.
