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 can be used in the surface modification of poly(ether sulfone) based ultrafiltration (UF) membrane as a foul-resistant material.
