Protein–polymer hybrids: Conducting ARGET ATRP from a genetically encoded cleavable ATRP initiator

European Polymer Journal, 2013
Abstract 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.

Cell-Adhesive Star Polymers Prepared by ATRP

Biomacromolecules, 2009
This 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, 2013
The 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, 2011
Photoinduced 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.

Common Acronyms AAC ‐ ATRP

ChemInform, 2007
AbstractThe ChemInform list of common acronyms contains more than 800 acronyms of chemical substances which have been gathered from about 100 chemical journals. In view of the thousands of acronyms devised by authors in the chemical literature, this list is certainly not complete, but it may prove to be useful for the identification of the more common ...

Alkylation of polyethyleneimine for homogeneous ligands in ATRP

Polymer, 2011
Abstract Ethylated and butylated polyethyleneimine ligands were synthesized and employed in copper catalyzed atom transfer radical polymerization of styrene and methyl methacrylate with suitable initiators in order to obtain homogeneous polymerizations, resulting in well defined polymers with low polydispersities.

Rate‐enhanced ATRP in the presence of catalytic amounts of base: An example of iron‐mediated AGET ATRP of MMA

Journal of Polymer Science Part A: Polymer Chemistry, 2011
AbstractThe catalytic amount of inorganic bases (i.e., NaOH, Na3PO4, NaHCO3, and Na2CO3) and organic bases such as pyridine and triethylamine was used as the additives in an iron‐mediated atom transfer radical polymerization with activators generated by electron transfer (AGET ATRP) of a polar monomer methyl methacrylate (MMA) using FeCl3·6H2O as the ...

Protein–Polymer Conjugates as Biocompatible and Recyclable ATRP Catalysts

Biomacromolecules
Atom transfer radical polymerization (ATRP) is a leading method for creating polymers with precise control over molecular weight, yet its reliance on metal catalysts limits its application in metal-sensitive and environmental contexts. Addressing these limitations, we have developed a recyclable, biocompatible, robust, and tunable ATRP catalyst ...
