Poly(ethylene oxide), MW 100000 (PEO 100K)
(-CH2CH2O-)n
Polyethylene oxide (PEO 100000) is a water-soluble polymer in a white, free flowing powder. Used to impart viscosity to and modify flow of aqueous solutions. See poly(ethylene glycol) for lower molecular weight analogs. Poly(ethylene oxide) has a broad molecular weight distribution ranging from~ 0.5x to 1.5x the values shown.
Soluble in: acetone, alcohol, chloroform, toluene, dichloromethane
PEO 100K contains: BHT 0.01%, SiO2 1.5% max, alkaline earth oxide as CaO 0.5%.Vaia, R. A., Vasudevan, S., Krawiec, W., Scanlon, L. G. & Giannelis, E. P.
