Controlled “living” anionic polymerization of glycidyl methacrylate

Activator Generated Electron Transfer Combined Atom Transfer Radical Polymerization (AGET-ATRP) for Controlled Grafting Location of Glycidyl Methacrylate on Regenerated Cellulose Ultrafiltration Membranes

This investigation indicates the ability to selectively graft glycidyl methacrylate (GMA) only from the external surface of regenerated cellulose (RC) ultrafiltration (UF) membranes using activator generated electron transfer (AGET) atom transfer radical polymerization (ATRP). This controlled polymerization resulted in epoxy functionalized polymer brush ends. Further reaction of the terminal ep...

Kinetics of Living Anionic Polymerization of Polystyrenyl Lithium in Cyclohexane

Living anionic polymer chains polymerized with organolithium initiators usually form aggregates through their Li ends in nonpolar solvents. This aggregation structure strongly affects the anionic polymerization (propagation) kinetics. In the conventional molecular picture, the aggregates are assumed to be chemically inert and the propagation occurs only though the dissociated unimers, which lea...

Extreme UV Radiation Grafting of Glycidyl Methacrylate Nanostructures onto Fluoropolymer Foils by RAFT-Mediated Polymerization

Periodic nanostructures of poly(glycidyl methacrylate) (pGMA) were grafted onto poly(ethylenealt-tetrafluorethylene) (ETFE) films by reversible addition-fragmentation chain transfer (RAFT) polymerization. ETFE samples were first irradiated in an interference lithographic setup using EUV (extreme ultraviolet) light followed by exposure to air to introduce surface peroxide groups serving as therm...
