“…Epoxy resins of symmetric double Schiff bases (I) were synthesized and purified according to our recent publication [22]. Molecular weights and molecular weight distributions were determined by gel permeation chromatography [22]. The epoxy resins ESDSB-1, ESDSB-2 and ESDSB-3 used in the present investigation had weight average molecular weights of 7460, 2570 and 7730 g·mol −1 , respectively.…”

The density, viscosity and ultrasonic speed (2 MHz) of several pure solvents: chloroform, THF, and 1,4-dioxane, along with epoxy resin solutions, have been investigated in order to understand the effect of solvents on molecular interactions in these systems at 308.15 K. Various thermodynamic parameters such as the ultrasonic speed (U ), adiabatic compressibility (κ α ), Van der Waals constant (b), internal pressure (π), intermolecular free path length (L f ), and viscous relaxation time (τ ) have been determined and correlated with the concentration (C). Good-to-excellent correlations are observed between a given parameter and the concentration. Linear or nonlinear increases or decreases of thermodynamic parameters with concentration indicated the existence of strong molecular interactions in the solutions. Gibb's energy of activation was found to be dependent on the concentration, nature of the solutes, and the solvents used.

The choice of basic epoxy resin (ER) is especially important for the design of epoxy adhesive formulations. In the present study, performance of several high-temperature ER systems, prepared using 4,4-diaminodiphenylsulfone as the curing agent by the same curing process, was investigated. The curing behavior was studied by dynamic rheometry and differential scanning calorimetry. The thermal properties of the cured resins were investigated by dynamic thermomechanical analysis, thermomechanical analysis, and thermogravimetric analysis. The peeling properties, mechanical behaviors, and moisture absorptivities of the cured resins were also studied. The results showed traditional diglycidyl ether of bisphenol A epoxy to be insufficient in heat resistance. Naphthalene-based ER and bifunctional cardo ER showed higher glass transition temperature values. However, the processability and adhesive properties may not comply with the application requirements. Biphenyl novolac ER has excellent performance in all aspects, which is suitable for use as a high-temperature adhesive.
