Acrylate-PEG-OH (Acrylate-PEG-Hydroxy) is a linear heterobifunctional PEG derivative containing an acrylate at one end and a hydroxyl group at the other, a reactive group that can be altered to form many functional groups. Free radical initiators readily polymerize acrylates. It is widely used in medical research, drug release, nanotechnology and new material research, cell culture.
