Descrição

Descrição geral

Polyethylene glycol (PEG) is a versatile and non-ionic polymer commonly used in a range of industrial and pharmaceutical applications due to its low toxicity, hydrophobic nature, and semicrystalline structure. It is made up of CH₂-CH₂O repeating units and its ability to exist in both monomer and aqueous phases at high temperatures makes it valuable for a range of research applications.
