Kinetic Modeling of ICAR ATRP [PDF]
Macromolecular Theory and Simulations, 2011 AbstractKinetic modeling is used to better understand and optimize initiators for continuous activator regeneration atom‐transfer radical polymerization (ICAR ATRP). The polymerization conditions are adjusted as a function of the ATRP catalyst reactivity for two monomers, methyl methacrylate and styrene.

Rapidly self-deoxygenating controlled radical polymerization in water via in situ disproportionation of Cu(i) [PDF]
, 2020 Rapidly self-deoxygenating Cu-RDRP in aqueous media is investigated. The disproportionation of Cu(I)/Me6Tren in water towards Cu(II) and highly reactive Cu(0) leads to O2-free reaction environments within the first seconds of the reaction, even when the ...

Fast Bulk Depolymerization of Polymethacrylates by ATRP
ACS Macro Letters, 2023 Fast bulk depolymerization of poly(n-butyl methacrylate) and poly(methyl methacrylate), prepared by atom transfer radical polymerization (ATRP), is reported in the temperature range between 150 and 230 °C. Depolymerization of Cl-terminated polymethacrylates was catalyzed by a CuCl2/TPMA complex (0.022 or 0.22 equiv vs P-Cl) and was studied using TGA ...

Ultrasound-Mediated Atom Transfer Radical Polymerization (ATRP) [PDF]
Materials, 2019 Ultrasonic agitation is an external stimulus, rapidly developed in recent years in the atom transfer radical polymerization (ATRP) approach. This review presents the current state-of-the-art in the application of ultrasound in ATRP, including an initially-developed, mechanically-initiated solution with the use of piezoelectric nanoparticles, that next ...

Metal-free atom transfer radical polymerization with ppm catalyst loading under sunlight
Nature Communications, 2021 Organocatalytic atom transfer radical polymerization (O-ATRP) is attractive due to its metal-free nature but catalysts are rarely applied at a low loading. Here the authors introduce a catalyst design logic based on heteroatom-doping of polycyclic arenes,
