产品描述： General description 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.
