Abstract

Epoxidised natural rubber ( ENR) has been prepared and used as a blending ingredient together with a compatibiliser for blending of natural rubber lair dry sheet, ADS) and cassava starch. Mooney viscosities of the blends were quantified at 100 degreesC and rheological properties in terms of shear stress and shear viscosity were plotted against shear rates. The results showed that pure ENR gave a lower Mooney viscosity, shear stress, and shear viscosity than blends with cassava starch. Mooney viscosity, shear stress, and shear viscosity For the blends increased with increasing levels of starch. At the same level of cassava starch blended. the highest values of these quantities were observed for the blends with ENR. The blend of ADS with ENRas a compatibiliser showed lower values than those of ENR itself, but higher than those of ADS with the starch. The results are described in terms ofthe level of chemical interaction between polar groups in ENR and in cassava starch. Curing behaviour for compounds of ENR. ADS. and ADS with ENR as compatibiliser were studied. The results found that ENR exhibited a long delay (similar to 10 min) before the vulcanisation took place compared with 1min for ADS compounds. In the curing curve for ENR, an equilibrium value at maximum torque was not found indicating that the stiffness of the ENR compounds still increased with increasing testing time until 60 min. Stiffnessof the ENR compounds also increased with increasing levels of cassava of the starch.
