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 ...
In the case of RDRP reactions in the presence of Cu(0), one of the mechanistic models proposed in the literature is called the supplemental activator and reducing agent atom-transfer radical polymerization (SARA ATRP). [10] [13] [14] The SARA ATRP is characterized by the traditional ATRP reactions of activation by Cu(I) and deactivation by Cu ...

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 ...
The steady-state concentration of the growing polymer chains is 10 −7 M by order of magnitude, and the average life time of an individual polymer radical before termination is about 5–10 s. A drawback of the conventional radical polymerization is the limited control of chain architecture, molecular weight distribution, and composition.

On May 2, 2017, Microsoft unveiled Windows 10 S (referred to in leaks as Windows 10 Cloud), a feature-limited edition of Windows 10 which was designed primarily for devices in the education market (competing, in particular, with ChromeOS netbooks), such as the Surface Laptop that Microsoft also unveiled at this time. The OS restricts software ...
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.
