polüetüleenoksiidi

Polüetüleenoksiid (PEO) is a water-soluble polymer produced by the ring-opening polymerization of ethylene oxide. It is a linear ether with the general formula H-(OCH2CH2)n-OH. PEO exists as a viscous liquid or a waxy solid depending on its molecular weight. It is known for its non-ionic nature and excellent biocompatibility.

PEO exhibits a range of properties that make it useful in various applications. Its high molecular weight grades are soluble in water and other polar solvents, while lower molecular weight grades can be soluble in a wider range of solvents. PEO is a viscoelastic material, meaning it exhibits both viscous and elastic characteristics when deformed. Its low toxicity and biodegradability have led to its use in biomedical fields.

Key applications of PEO include its use as a flocculant in water treatment, a binder in ceramics and pharmaceuticals, and a component in personal care products such as cosmetics and toothpaste. In medicine, PEO is employed in drug delivery systems, wound dressings, and as a lubricant for medical devices due to its biocompatibility. Its ability to form gels and its rheological properties also make it valuable in various industrial processes. The specific properties of PEO, such as its molecular weight and viscosity, can be tailored to suit the requirements of different applications.
