Mechanism of Halogen Exchange in ATRP
Macromolecules, 2011Detailed 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...

This review summarizes the recent progress on the synthesis and application of covalently crosslinked hydrogels prepared using atom transfer radical polymerization (ATRP) technique. ATRP has been employed as an effective means to synthesize well-controlled polymeric materials with narrow molecular weight distributions, compositions, chain-end ...

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-

How are Radicals (Re)Generated in Photochemical ATRP?
Journal of the American Chemical Society, 2014The polymerization mechanism of photochemically mediated Cu-based atom-transfer radical polymerization (ATRP) was investigated using both experimental and kinetic modeling techniques. There are several distinct pathways that can lead to photochemical (re)generation of Cu(I) activator species or formation of radicals.

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.

Metal-free ATRP “grafting from” technique for renewable cellulose graft copolymers
Green Chemistry, 2019Photoinduced metal-free “grafting from” atom transfer radical polymerization (ATRP) has been successfully applied to the fabrication of renewable cellulose graft copolymers with the aid of 2-bromo-2-phenylacetyl ester-modified ethyl cellulose as the ...

Cell-Adhesive Star Polymers Prepared by ATRP
Biomacromolecules, 2009This study presents the synthesis and evaluation of cell adhesive poly(ethylene oxide) (PEO) star polymers for potential biomedical applications. Star polymers with a size of approximately 20 nm and with relatively low polydispersities (M(w)/M(n) ≤ 1.6), containing GRGDS (Gly-Arg-Gly-Asp-Ser) segments, were prepared by atom transfer radical ...

Synthesis of polyacrylonitrile using AGET-ATRP in emulsion
Materials Science and Engineering: C, 2013The technique of activators generated by electron transfer for atom transfer radical polymerization (AGET-ATRP) of acrylonitrile (AN) has been first attempted in emulsion using the procedure of "one-pot", "two-step" with polyethylene glycol monooleyl ether (Brij 35) as surfactant, cupric chloride (CuCl2) as catalyst, hexamethylenetetramine (HMTA) as ...

Studies on Photoinduced ATRP in the Presence of Photoinitiator
Macromolecular Chemistry and Physics, 2011Photoinduced reverse and simultaneous reverse and normal initiation (SR&NI) atom transfer radical polymerization (ATRP) of methyl methacrylate are investigated. Compared to the photoinduced reverse ATRP, SR&NI ATRP allows for better control over molecular weight with narrow molecular weight distributions.
