Abstract: PEG can be synthesized via anionic polymerization of ethylene oxide and any hydroxyl initiators. Hydroxyl group could be from water or ethylene glycol or any diols. They can also be derived from epoxyethane by ring-opening polymerization. Usually, the polymerization process produces a family of PEG molecules with wide Gaussian's distribution of molecular weights. PEG bears only two functional groups limiting the scope for further derivatization with other residues or targeting ligands. Therefore, commercial PEGs are available with different degrees of polymerization and activated functional groups.Summary: Polyethylene glycol (PEG), a compound composed of repeated ethylene glycol units [-(CH2CH2O)n], is also known as Macrogols. PEG and PEG derivatives have the characteristics of non-irritation, good water solubility, good compatibility, etc. . At the same time, they possess excellent lubricity, moisture retention and dispersibility so that they can be used as adhesives, antistatic agents and softeners, and widely applied in cosmetics, pharmaceuticals, chemical fibers, rubber, plastics, paper, painReport abuse »
