The K ATRP value depends on the homo-cleavage energy of the alkyl halide and the redox potential of the Cu catalyst with different ligands. Given two alkyl halides (R 1-X and R 2-X) and two ligands (L 1 and L 2), there will be four combinations between different alkyl halides and ligands. Let K ij ATRP refer to the K ATRP value for R i-X and L ...
Krzysztof "Kris" Matyjaszewski (Polish: [ˈkʂɨʂtɔf matɨjaˈʂɛfskʲi]; born April 8, 1950) is a Polish-American [1] chemist.He is the J.C. Warner Professor of the Natural Sciences at the Carnegie Mellon University [2] Matyjaszewski is best known for the discovery of atom transfer radical polymerization (ATRP), a novel method of polymer synthesis that has revolutionized the way ...

Although copper complexes (in combination with relevant ligands) have long been used as catalysts for organic reactions such as atom transfer radical addition (ATRA) and copper(I)-catalyzed alkyne-azide cycloaddition (CuAAC), copper complex catalyzed RDRP was not reported until 1995 when Jin-Shan Wang and Krzysztof Matyjaszewski introduced it as atom transfer radical polymerization (ATRP).
There is a mode of polymerization referred to as reversible-deactivation polymerization which is distinct from living polymerization, despite some common features. Living polymerization requires a complete absence of termination reactions, whereas reversible-deactivation polymerization may contain a similar fraction of termination as conventional polymerization with the same concentration of ...
ATRP involves the chain initiation of free radical polymerization by a halogenated organic species in the presence of a metal halide. The metal has a number of different oxidation states that allows it to abstract a halide from the organohalide, creating a radical that then starts free radical polymerization.
Azedo Gneco at a republican gathering in Lisbon in 1907. Eudóxio César Azedo Gneco (21 June 1849 in Samora Correia [], Benavente – 29 June 1911 in Lisbon), better known as Azedo Gneco, was an Italian-Portuguese engraver, medalist, apprentice sculptor and political activist.
