| Résumé : |
Ultrasonic velocity and related parameters of solutions of synthesized epoxy resins (bisphenol and glycerol based, having different molecular weights) in 1,4-dioxane at 303.15K have been evaluated in the concentration range 0.5-24 % by weight, at 3 MHz in order to understand the molecular interactions and to get information on structural aspects. Bisphenol based epoxy resins showed polymer-solvent interactions at lower concentrations, while polymer-polymer type interactions dominated at higher concentrations. Glycerol based epoxy resin indicated different behaviour as the polymeric molecules interacted strongly and associated even at lower concentrations. |
