Description

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.

Application

PEGMA can be used in the development of molecular brushes as a substrate material for stimuli-responsive surfaces in biomedical applications. It may be used in the surface modification of poly(ether sulfone) based ultrafiltration (UF) membrane as a foul-resistant material.
