General description

Poly(ethylene glycol) methyl ether methacrylate (PEGMA) is a nonlinear analog of polyethylene glycol (PEG). It is a biocompatible homopolymer with a brush type structure that is mainly used to provide a PEG modified surface.


PEGMA may be used in the preparation of a polyelectrolytic solution for the development of lithium ion batteries. It can be photopolymerized to form a zwitterionic monomer which can be coated on steel surfaces for bio-fouling based applications.
