Abstract

The Thermal stability and solvent transport properties of elastomeric blends of natural rubber and exudated resin of Ailanthus Malabaricum tree were studied in detail. The elastomeric blend samples have been prepared from solution casting technique. Benzene was used as a common solvent for both the constituent polymers to prepare the blends. The resulting material exhibits excellent elastic properties. Thermogravimetry was employed to analyze the thermal stability of natural rubber by the addition of resin. The temperatures at various weight losses for different samples were determined from Thermogravimetric curves. The activation energy of degradation was calculated from Horowitz Metzger equation. The addition of natural rubber improves the thermal stability of resin. The solvent transport properties of the resulting samples were studied in benzene. The combination of natural rubber and the resin exudated from Ailanthus Malabaricum tree can be used to prepare the elastomeric material with suitable properties for specific applications.
