Ultrasound-Mediated Atom Transfer Radical Polymerization (ATRP). [PDF]

open access: yesMaterials (Basel), 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

open access: yesNature 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,
