Polyox – 50 g Pack

Polyox (polyethylene oxide) is a completely non‑toxic, high‑molar‑mass, long‑chain polymer known for its remarkable physical behaviour. Due to extensive hydrogen bonding, Polyox dissolves readily in water to form highly viscous solutions with unique and fascinating properties ideal for classroom demonstrations and polymer science experiments.

A ~1% w/v solution of Polyox behaves as an “elastic liquid”. One of its most striking features is its ability to self‑siphon: if a small amount of solution is dragged out of a beaker using a spatula or spoon, the rest of the liquid continues to flow out on its own. It can even be drawn into a syringe from below the tip, appearing to defy gravity as it climbs upward.

Only 5 g is needed to produce approximately 500 cm³ of Polyox solution, making this 50 g pack excellent value for repeated use or larger experimental setups.

Please note: preparation typically requires propan‑2‑ol (commonly available in schools) to assist dispersion, and the use of a magnetic stirrer is strongly recommended for best results.
