2-Arm-PEG-Methacrylate

2-Arm methacrylate-functionalized discrete poly(ethylene glycol) (2-Arm-PEG-Methacrylate) is a 2-arm precision PEG derivative. The PEG arms present terminal methacrylate groups. Discrete chain lengths with different degrees of polymerization are available. The methacrylate can undergo radical polymerization or copolymerization, covalently incorporating the PEG segment into polymer materials. The multiarm structure provides attachment sites for multivalent ligand display or network construction. Arm number, chain length, and functional-group equivalents can be varied to compare crosslink spacing and molecular presentation. In this series, n denotes the number of ethylene glycol repeat units in each PEG arm.
