【 摘 要 】

Thermal properties of weight loss and melting temperatures for samples of Parkia Powder (PP) and its blend with Poly(vinyl pyrrolidone) (PVP) at 50 weight percentage have been studied using TGA and DSC. The samples are characterized by using FTIR over the range of 4000-500 wave numbers (cm-1). The optical absorption for these samples is also studied using UV-vis Spectrometer over the range of 200-750 nm. The absorption edge of PP is 229 nm and that of PVP is 257 nm, but for their blend absorption edge shifted to 338 nm.
