Description and Uses

Poly(ethylene glycol) bis(carboxymethyl) ether is a high molecular weight polyether carboxamide used as an extracellular corrosion inhibitor and fluorescence assay for the detection of polyols in macroscopic samples. It is also used in the synthesis of poly(ethylene glycol) bis(carboxymethyl) ether, also known as PEG bis(carboxymethyl) ether, a polymer of poly(ethylene glycol) (PEG) with carboxylic acid functional groups at the ends of the polymer chain.

Poly(ethylene glycol) bis(carboxymethyl) ether may used as a plasticizer.
