The heat change analysis was performed using DSC (Differential scanning calorimetry) at a temperature range 10 °C -320 °C shown in Figure . The upward peaks were generated for endothermic behaviour at that particular temperature range, while the downward peaks for exothermic behaviour. The first peak (upward), which also the highest peak, was observed at around 90 °C for both the samples WMP and UMP; second peak (upward) at near 200 °C for UMP; while third peak (downward) at near 222 °C for WMP. However, WMP required slightly higher heat flow than UMP for temperature ranges around 10 °C -100 °C, 120 °C -180 °C, and 260 °C -320 °C. For temperature range around 100 °C -120 °C, 230 °C -260 °C, both WMP and UMP have almost equal heat flow; for temperature 180 °C -230 °C, WMP required slightly lower heat flow than UMP. Thus, WMP has shown more endothermic nature compared to UMP for the temperature ranges 10 °C -100 °C, 120 °C -180 °C, and 260 °C -320 °C, whereas WMP also showed more exothermic nature than UMP for temperature range around 180 °C -230 °C.
