Effect of Ultraviolet Irradiation on Molecular Structure of High Density Polyethylene
Abstract:
The structure change of HDPE under ultraviolet irradiation in air and O2 atmosphere was studied by elemental analysis, FTIR, XPS, GPC.The oxygen containing groups such as C=O C-O were observed in molecular chains of HDPE after irradiation.The contents of C=O and C-O increase with irradiation time.The O2 acceleretes the rate of HDPE functionalization.During ultraviolet irradiation, the molecular weight of HDPE is decreased and its MWD becomes narrow.
