HDPE, additives Antistatic agents

Polyethylene glycols (PEG) are used as antistatic agents in polyethylene (PE) resins. PEG is a difficult additive to analyse. It cannot be extracted either quantitatively or reproducibly. A simple, rapid and reliable method is required for PEG in PE. Kumar [10] has described a direct Fourier transform infrared (FTIR) spectrometric approach for successfully determining low concentrations (<0.05% m/m) of Garbowax (PEG 400) in high-density polyethylene (HDPE).
