Thermo-oxidative Degradation of High Density Polyethylene Containing Manganese Carboxylate

This paper reports the study of utilization of manganese laurate for accelerating the degradation process of high density polyethylene (HDPE). Specimens were prepared by loading manganese laurate from 0 to 1%(w/w) in HDPE resins using twin screw extruder followed by injection molding. Thermal treat...
