Polyethylene glycol (C09-0999-373)

Polyethylene glycol (PEG) is a hydrophilic polymer. It can be easily synthesized by the anionic ring opening polymerization of ethylene oxide, into a range molecular weights and variety of end groups. When crosslinked into networks PEG can have high water content, forming "hydrogels". Hydrogel formation can be initiated by either crosslinking PEG by ionizing radiation or by covalent crosslinking of PEG macromers with reactive chain ends. PEG is a suitable material for biological applications because it does not trigger an immune response.Usually used to modify therapeutic proteins and peptides to increase their solubility and lower their toxicity. Solvent for greener fluorination of acetoacetamides with Selectfluoapplication：Polyethylene glycol is used in the modification of therapeutic proteins and peptides to enhance its solubility. It is also used in the fabrication of bioactive and immuno isolating barriers for encapsulation of cells. In Gas chromatorgraphy, it is used as a polar stationary phase. It is used as mold release agent and lubricant in fabricating elastomers.
