PEG is formed from several repeating units of its <scene name='Erika_M._Saffer/sandbox1/Peg_monomer/1'>monomer</scene>, ethylene glycol (C2H6O2). During polymerization, the ethylene glycol monomers chemically link together to form a long chain, referred to as a <scene name='Erika_M._Saffer/sandbox1/Peg_400mw/2'>polymer</scene>. The polymerization process can be controlled, allowing for the formation of a wide range of molecular weights. PEG is biocompatible at low molecular weights. When these polymers are end functionalized, they can crosslink with one another and form a network. Due to the hydrophilic nature of PEG, when this network is in the presence of water it will swell to form a hydrogel. The physical properties of these hydrogels make them excellent candidates for use as tissue engineering scaffolds and in other biomaterial applications. | PEG is formed from several repeating units of its <scene name='Erika_M._Saffer/sandbox1/Peg_monomer/1'>monomer</scene>, ethylene glycol (C2H6O2).
