Dope new organocatalysts for ATRP
Nature Reviews Chemistry, 2021A re-evaluation of the design principles of organocatalysts for atom transfer radical polymerization has led to the development of heteroatom-doped polycyclic arenes as highly active photocatalysts.

Macromolecules, 2012
Activators regenerated by electron transfer atom transfer radical polymerization (ARGET ATRP) was successfully implemented in aqueous media for the first time. A well-controlled polymerization of oligo(ethylene oxide) methyl ether methacrylate (OEOMA) was conducted with 300 ppm or lower of a copper catalyst and tris(2-pyridylmethyl)amine (TPMA) ligand ...

Kinetic Modeling of Normal ATRP, Normal ATRP with [CuII]0, Reverse ATRP and SR&NI ATRP
Macromolecular Theory and Simulations, 2008AbstractThe kinetics of various ATRP systems, including normal ATRP, normal ATRP in the presence of initially‐added CuII, reverse ATRP and SR&NI ATRP were modeled using Predici software. The instantaneous kinetic chain length was introduced for ATRP and was used for the prediction of control over polymerization.

Advantages of Surface‐Initiated ATRP (SI‐ATRP) for the Functionalization of Electrospun Materials
Macromolecular Rapid Communications, 2012AbstractSurface‐initiated atom transfer radical polymerization (SI‐ATRP) is successfully applied to electrospun constructs of poly(L‐lactide). ATRP macroinitiators are adsorbed through polyelectrolyte complexation following the introduction of negative charges on the polyester surface through its blending with a six‐armed carboxy‐terminated ...

High Molecular Weight PMMA by ATRP
Macromolecules, 2002Atom transfer radical polymn. kinetics was examd. in a high monomer-initiator ratio system to evaluate the possibility of obtaining low polydispersity high mol. wt. polymethyl methacrylate by a one-pot synthesis. Three different ligands were examd., N,N,N',N\",N\"-pentamethyldiethyltriamine (PMDETA), 4,4'-n-nonyl-2,2'-bipyridine, (dnNbpy,) and 2 ...

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.

Supported ATRP and giant polymers
Chemical Communications, 2003Surface-initiated Atom Transfer Radical Polymerization (ATRP) produces surface-bound films with thicknesses up to tens of microns. We report on the possible existence of micron-sized, individual polymer chains in these films.
