Blends consisting of a systematic compositional series of Sago Starch (SS) and chitosan (CS) were studied by using a Brookfield Digital Viscometer Model DV-II Version 2.0. The viscosity of pure SS, pure CS and SS/CS blends was measured over the temperature range 30-130 °C. Results on the SS/CS blends indicate that the viscosity decreases with temperature and SS content for a fixed speed. At lower SS content, the decrease of viscosity with temperature is more pronounced. This indicates that blends with higher CS content are more affected by temperature changes. Blend containing 50%CS was superior compared to other blends and this finding is consistent with earlier works on compatibility studies of polypropylene/sago starch blend using Dynamical Mechanical Thermal Analyzer (DMTA).
