ATRP with ppb Concentrations of Photocatalysts. [PDF]

J Am Chem Soc
In atom transfer radical polymerization (ATRP), dormant alkyl halides are intermittently activated to form growing radicals in the presence of a CuI/L/X-CuII/L (activator/deactivator) catalytic system. Recently developed very active copper complexes could decrease the catalyst concentration to ppm level. However, unavoidable radical termination results

Disproportionation or Combination? The Termination of Acrylate Radicals in ATRP [PDF]

Macromolecules, 2017
The termination of acrylate radicals in atom transfer radical polymerization (ATRP) can involve either conventional bimolecular radical termination (RT) or catalytic radical termination (CRT). These processes were investigated using a poly(methyl acrylate)–Br macroinitiator under different initial conditions tuned to change the RT/CRT ratio.

Photoinitiated ATRP in Inverse Microemulsion

Macromolecules, 2013
The recently developed photoinitiated atom transfer radical polymerization has been implemented in the inverse microemulsion polymerization of oligo(ethylene glycol) monomethyl ether methacrylate. Two different mechanisms including a simultaneous reverse and normal initiated ATRP and a combination of activators generated by electron transfer and ...
