A new end group structure of poly(ethylene glycol) for hydrolysis‐resistant biomaterials

Abstract

A new PEG end-group structure (α-PEG-MA) was designed and synthesized. When compared with the conventionally used PEG-acrylate structure, the vinyl group in the new structure showed comparable reactivity in thiol-ene reactions, but the formed materials were hydrolysis resistant because there is no ester linkage in the backbone chains.
