General description

Polyethylene glycol (PEG) is a suitable material for biological applications since it does not trigger an immune response. It can by synthesized by anionic ring opening polymerization of ethylene oxide with a range of end groups (such as methacrylate: PEGMA) attached. PEG is a hydrophilic polymer that can form hydrogels when cross linked into networks. Acrylate and methacrylate chain ends undergo chain polymerization to from PEGMA hydrogels.
