Rapidly self-deoxygenating controlled radical polymerization in water via in situ disproportionation of Cu(i) [PDF]

open access: yes, 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 ...
