What is PEG diacrylate (PEGDA) used for?

PEGDA is widely used as a crosslinkable PEG macromer for forming polymer networks, including PEG-based hydrogels, via radical polymerization.

What does “diacrylate” mean in PEGDA?

“Diacrylate” indicates the PEG chain is end-functionalized with two acrylate groups, enabling it to form crosslinks and build a network during polymerization.

How does PEG molecular weight affect the network properties?

PEG molecular weight can influence network mesh size and flexibility. Lower molecular weight PEGDA typically forms denser networks; higher molecular weight PEGDA can form networks with larger spacing between crosslinks.

What is the difference between PEGDA and PEGDMA?

PEGDA uses acrylate end groups, while PEGDMA uses methacrylate end groups. Acrylates often polymerize faster than methacrylates under similar radical conditions.
