Isoquinoline-based acid/base switchable RAFT agents (SRAs) were synthesized and used as new photoiniferters for visible light-controlled polymerization. In contrast to commercially available pyridyl-substituted SRAs, isoquinoline-based SRAs absorb green light more strongly, exhibit higher pKa values, offer rates of photolysis. Photoiniferter polymerization was conducted in the presence either blue or at 25 °C. A faster rate observed syntheses using than SRAs. Polymers with controlled molecular weights tunable dispersities prepared varying amounts 4-toluenesulfonic acid. Four pseudoblock poly(methyl acrylate)s dispersity via chain extension experiments. Well-defined diblock copolymers consisting a activated monomer (methyl acrylate) less (N-vinylpyrrolidone) can be relatively low dispersities.

Atom transfer radical polymerization (ATRP) is one of the most often used controlled techniques. It employs very small amounts (ppm) Cu complexes in presence various chemical reducing agents but also external stimuli such as light, electrical current or mechanical forces. can be carried out bulk, solution, and dispersed media. ATRP has been successfully to prepare polymers with architecture well-defined topology, composition, functionality, well bioconjugates organic–inorganic hybrids. This article summarizes status an outlook for ATRP.
