Externally controlled atom transfer radical polymerization

Chemical Society Reviews, 2018
ATRP can be externally controlled by electrical current, light, mechanical forces and various chemical reducing agents. The mechanistic aspects and preparation of polymers with complex functional architectures and their applications are critically reviewed.

Macromolecular Engineering by Atom Transfer Radical Polymerization

Journal of the American Chemical Society, 2014
This Perspective presents recent advances in macromolecular engineering enabled by ATRP. They include the fundamental mechanistic and synthetic features of ATRP with emphasis on various catalytic/initiation systems that use parts-per-million concentrations of Cu catalysts and can be run in environmentally friendly media, e.g., water.

Monomode Microwave‐Assisted Atom Transfer Radical Polymerization

Macromolecular Rapid Communications, 2004
AbstractSummary: The first monomode microwave‐assisted atom transfer radical polymerization (ATRP) is reported. The ATRP of methyl methacrylate was successfully performed with microwave heating, which was well controlled and provided almost the same results as experiments with conventional heating, demonstrating the absence of any “microwave effect” in

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 ...

Radical Nature of Cu-Catalyzed Controlled Radical Polymerizations (Atom Transfer Radical Polymerization)

Macromolecules, 1998
Copper-catalyzed atom transfer radical polymerization (ATRP) is one of the most robust and precise techniques for controlling radical polymerization. The very good control of molecular weights, polydispersities, functionalities, chain composition, and topologies unusual for radical systems combined with the application of transition metals as catalysts

Atom transfer radical polymerized MR fluids

Polymer, 2006
Abstract A novel magnetorheological fluid, in which the surface of iron particles is coated with poly(butyl acrylate) by surface-initiated atom transfer radical polymerization (ATRP), is investigated. The polymer coating procedure includes two steps, which are immobilization of initiator: 2-(4-chlorosulfonylphenyl)-ethyltrichlorosilane (CTCS) on the ...

Dithioesters in atom-transfer radical polymerization

Polymer Science Series B, 2006
Phenyl dithioacetates and bis(isobutyl) dithiocarbamates of Cu(II) and Ti(IV) were studied as chain-transfer agents in the controlled free-radical polymerization of methyl methacrylate and styrene. It was shown that the above compounds strongly decelerate the polymerization of at least one of the monomers.
