Poly(ethylene glycol) (PEG) is a thermoplastic polymer with a relatively simple chemical structure. It is semicrystalline, water-soluble, and biocompatible. (1,2) It has good lubrication properties, appropriate water retention, and low toxicity. Depending on the molar mass, the melting temperature of PEG varies from 0 to 65 °C. (3) Thus, low-molar-mass samples are liquid at room temperature, whereas high-molar-mass samples are solid.
