Description

General description

Poly(ethylene glycol) (PEG) dimethacrylate is a homobifunctional, hydrophilic, biocompatible polymer commonly used as a crosslinker in PEG hydrogels. Crosslinked networks can be formed via radical initiator induced polymerization or photopolymerization.

Application

PEG dimethacrylates have numerous applications including tissue engineering, 3D printing applications, surface modifications, PEGylation of proteins and peptides, and drug delivery.
