Optimization of antistatic additives in polypropylene

Abstract The antistatic behavior of glyceryl monoesters in polypropylene (PP) is measured at concentrations down to 0.30 wt%. Water contact angles and XPS analyses are used to explore the mechanism of internal antistats. Orientation of glyceryl monostearate (GMS) at the surface of PP is determined. Several new antistat compositions for PP are introduced.
