Intensifying the ATRP synthesis of statistical copolymers by continuous micromixing flow techniques1
Green Processing and Synthesis, 2012 The impact of micromixers on copolymers’ characteristics in a continuous-flow microprocess was studied. A stainless steel coiled tube was used as the microreactor.

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 ...

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 ...

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,

SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement
Advanced Functional Materials, EarlyView.An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...
