ARGET ATRP for Versatile Grafting of Cellulose Using Various Monomers
ACS Applied Materials & Interfaces, 2009In recent years, cellulose-based materials have attracted significant attention. To broaden the application areas for cellulose, polymers are often grafted to/from the surface to modify its properties. This study applies ARGET (activators regenerated by electron transfer) ATRP (atom transfer radical polymerization) when straightforwardly grafting ...

Grafting from Surfaces for “Everyone”: ARGET ATRP in the Presence of Air
Langmuir, 2007Atom-transfer radical polymerization (ATRP) is one of the controlled/living radical polymerizations yielding well-defined (co)polymers, nanocomposites, molecular hybrids, and bioconjugates. ATRP, as in any radical process, has to be carried out in rigorously deoxygenated systems to prevent trapping of propagating radicals by oxygen.

Thermo-responsive cellulose paper via ARGET ATRP
Fibers and Polymers, 2016Thermo-responsive poly(N-isopropylacryl-amide) (PNIPAM), was grafted from cellulose paper via activators regenerated by electron transfer atom transfer radical polymerization (ARGET ATRP). Six solvents with different polarities, including water, methanol, isopropanol, anisole, and methanol/H2O, isopropanol/H2O mixed solvents, were utilized to perform ...

Tuning Dispersity in Diblock Copolymers Using ARGET ATRP
Macromolecular Chemistry and Physics, 2012AbstractPoly(methyl acrylate)‐b‐polystyrene with controlled molecular weight distribution of each block was synthesized via activators regenerated by electron transfer atom transfer radical polymerization. Polymers with tunable dispersity, in the range of Mw/Mn 1.32 to 2.0, were achieved by adjusting the concentration of the copper catalyst and ...

The synthesis of water‐soluble PHEMA via ARGET ATRP in protic media
Journal of Polymer Science Part A: Polymer Chemistry, 2010Abstract2‐Hydroxyethyl methacrylate has been polymerized in methanol using activators regenerated by electron transfer (ARGET) atom transfer radical polymerization (ATRP), to produce water‐soluble poly(2‐hydroxyethyl methacrylate) (PHEMA). The various parameters that determine control of the living polymerization have been explored.

Synthesization and Characterization of Lignin-graft-Poly (Lauryl Methacrylate) via ARGET ATRP
International Journal of Biological Macromolecules, 2022Lignin as an abundant biological macromolecule isolated from the plant cell wall, and it cannot be efficiently utilized until suitable modifications to its structures were made. Therefore, we proposed a strategy to prepare an all biomass-based Lignin-graft-poly(Lauryl methacrylate, LMA) by grafting LMA monomers on the organosolv lignin through ARGET ...

Oligo(ethylene glycol) methacrylate (OEGMA) was polymerized from a polymerization initiator-presenting gold substrate by Activator ReGenerated by Electron Transfer Atom Transfer Radical Polymerization (ARGET ATRP) in water. Compared with the normal surface-initiated ATRP (SI-ATRP), SI-ARGET ATRP of OEGMA proceeded smoothly in the presence of air with L-

Protein–polymer hybrids: Conducting ARGET ATRP from a genetically encoded cleavable ATRP initiator
European Polymer Journal, 2013Abstract Protein–polymer hybrids are an important class of biomaterials. Described is the preparation of a genetically incorporated a non-canonical amino acid (nCAA) containing an ester linked atom transfer radical polymerization (ATRP) initiator, followed by a controlled “grafting from” polymerization.
