Atom transfer radical polymerization (ATRP): A versatile and forceful tool for functional membranes

Progress in Polymer Science, 2014
Abstract The progress in atom transfer radical polymerization (ATRP) provides an effective means for the design and preparation of functional membranes. Polymeric membranes with different macromolecular architectures applied in fuel cells, including block and graft copolymers are conveniently prepared via ATRP.

Modification of magnetite nanoparticles via surface-initiated atom transfer radical polymerization (ATRP)

Chemical Engineering Journal, 2008
Modification of magnetite nanoparticles via surface-initiated atom transfer radical polymerization (ATRP) was carried out. The magnetic nanoparticles with an initiator group for copper-mediated atom transfer radical polymerization, 3-aminopropyltriethoxysilane chemically bound on their surfaces were prepared by the self-assembled monolayer.

Ionic liquids as reaction media for polymerization processes: atom transfer radical polymerization (ATRP) of acrylates in ionic liquids

Polymer International, 2003
Abstract Application of ionic liquids (organic salts that are liquid at ambient temperatures) as solvents for atom transfer radical polymerization (ATRP) of acrylic monomers is described. Ionic liquids dissolve several inorganic and organic compounds, are highly polar and non‐volatile.

Cyclic polymers and catenanes by atom transfer radical polymerization (ATRP)

Polymer International, 2014
The topologically interesting structures of cyclic polymers, catenanes and other macrocycles are of much interest for their unique chemical and physical properties. However, it is a challenge to design synthetic routes that afford controlled ring structures and connectivity, which is why the practical applications of these materials have not been ...

Atom Transfer Radical Polymerization (ATRP)

2013
Atom transfer radical polymerization (ATRP) is a catalytic process mediated by a redox-active transition metal complex able to abstract homolytically a halogen atom from an alkyl halide in a reversible fashion. The mechanistic understanding of ATRP is crucial and enables the rational selection of reaction components and conditions needed for the ...

EPR study of the atom transfer radical polymerization (ATRP) of (meth)acrylates

Macromolecular Rapid Communications, 1998
Electron paramagnetic resonance (EPR) spectroscopy was applied to atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA) and methyl acrylate (MA) in order to investigate the mechanism of the controlled/“living” radical polymerization system.

Functionalization of Starch for Macro-Initiator of Atomic Transfer Radical Polymerization (ATRP)

Advanced Materials Research, 2014
Using of petro-polymers such as polymethylmethacrylate, polypropylene and polyethylene in the world has been undergoing a critical problem due to significantly decreasing of petroleoum stock as monomer sources. Therefore reducing of the petro-polymer usage should be performed by using natural resources such as modified starches.This study reported ...

Supported nickel bromide catalyst for Atom Transfer Radical Polymerization (ATRP) of methyl methacrylate

Chem. Commun., 2004
A new supported catalytic system, i.e. nickel bromide catalyst ligated by triphenylphosphine (TPP) ligands immobilized onto crosslinked polystyrene resins (PS-TPP) is reported. Per se, this catalyst does not allow any control over the polymerization of methyl methacrylate (MMA) initiated by ethyl 2-bromoisobutyrate but, in the presence of a given ...
