Living CO₂-Switchable Latexes Prepared via Emulsion ATRP and AGET Miniemulsion ATRP

Macromolecules, 2016
Living CO2-switchable poly(methyl methacrylate) (PMMA) latexes were prepared using reverse ATRP emulsion polymerization and AGET ATRP miniemulsion polymerization. The prepared latexes can be switched between the aggregated and dispersed states using only CO2 and any nonacidic gas (e.g., argon, air, nitrogen) as triggers.

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 ...

Linear Gradient Quality of ATRP Copolymers

Macromolecules, 2012
The linear gradient quality and the control over chain length and end-group functionality in the copolymerization of acrylates, methacrylates, and styrenes via atom transfer radical polymerization (ATRP) are evaluated by detailed kinetic Monte Carlo simulations with explicit tracking of macromolecules.

Biocatalytic ATRP in solution and on surfaces

2019
The promiscuity of enzymes allows for their implementation as catalysts for non-native chemical transformations. Utilizing the redox activity of metalloenzymes under activator regenerated by electron transfer (ARGET) ATRP conditions, well-controlled and defined polymers can be generated.

Investigation of iron complexes in ATRP: Indications of different iron species in normal and reverse ATRP

Journal of Molecular Catalysis A: Chemical, 2011
In an attempt to correlate the ATRP kinetics and the redox properties of the mediator, eight iron complexes with nitrogen, phosphorous and carboxylic acid containing ligands were investigated by el ...

Polymer catenanes via a supramolecularly templated ATRP initiator

Chemical Communications, 2011
Synthesis of polymer catenanes via a living radical polymerization and supramolecular template approach are demonstrated. The ring closure was performed via atom transfer radical cross coupling (ATRC) to obtain polymer catenanes from the linear polymer metal complex precursor.

Mechanism of Halogen Exchange in ATRP

Macromolecules, 2011
Detailed mechanistic studies reveal that halogen exchange (HE) in ATRP can occur not only by a radical pathway (atom transfer) but also by an ionic pathway (SN2 reaction) because Cu(I)(L)X and Cu(I...

Solid-Phase ATRP Synthesis of Peptide−Polymer Hybrids

Journal of the American Chemical Society, 2004
A versatile methodology to prepare hybrid biomaterials by atom transfer radical polymerization from resin-supported peptides has been established. As an example, we have synthesized a GRGDS-functionalized poly(2-hydroxyethyl methacrylate). The peptide-polymer was characterized by solid-state (13)C NMR and GPC and found to have a number average ...
