Abstract:
The interest of present work is producing biopolymer-BP based on vegetable oil blended with high density polyethylene-HDPE by two different forms from particle-P and liquid-L forms namely as BPP and BPL respectively. Manufacturing ratio are varied based on BP weight percentages of 5, 10, 15, 20, 25 and 30 to HDPE. The prepared polymer blends are subjected to dynamic mechanical properties test in terms of storage modulus (E'), loss modulus (E”), and damping (Tan δ) at consistent frequencies of 1 Hz. The results indicated that by increasing the temperature and percentages of loading BPP and BPL, storage modulus (E') and loss modulus (E”) was decreased while for Tan δ, the glass transition temperature (T g ) was shifted to the left; lower temperature. The T g also shows single peak for every ratio of BP percentages which indicate that the blending process are produce miscible BPP and BPL.
