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.

Abstract Unlike classical radical polymerization, the kinetics of atom transfer polymerization show significant solvent dependence, possibly arising from effects on activation step. A kinetic study initiator ethyl α‐bromoisobutyrate by [Cu I TPMA] + (TPMA=tris(2‐pyridylmethyl)amine), an initiator/catalyst combination frequently used in ATRP, was carried out DMSO, DMF, MeCN, anisole, acetate, and their 50 vol % mixtures with styrene (STY) methyl methacrylate (MMA). k act values varying about 3 orders magnitude 3.14×10 5 mol −1 dm s DMSO to 9.41×10 2 acetate were found. These showed excellent correlation polarity/polarizability parameter π*. The effect MMA or STY depended polarity compatibility between monomer solvent: After addition, decreased considerably polar solvents, whereas it almost unaffected nonpolar solvents.

Solid-phase polymer synthesis, historically rooted in peptide has evolved into a powerful method for achieving sequence-controlled macromolecules. This study explores solid-phase synthesis by covalently immobilizing growing chains onto poly(ethylene glycol) (PEG)-based resin, known as ChemMatrix (CM) resin. In contrast to traditional hydrophobic supports, CM resin's amphiphilic properties enable swelling both polar and nonpolar solvents, simplifying filtration, washing, drying processes. Combining atom transfer radical polymerization (ATRP) with techniques allowed the grafting of well-defined block copolymers high yields. approach is attractive successfully synthesizing di-, tri-, tetra-, penta-block excellent control over molecular weight dispersity. The also delves limitations weights due confinement within resin pores. Moreover, versatility demonstrated through its applicability various monomers organic aqueous media. straightforward offers rapid route developing tailored unique structures functionalities.

Despite significant advancements in thermal and photothermal depolymerizations, the success of these techniques relies on tedious deoxygenation procedures. Herein, we report development depolymerization technique efficient without prior deoxygenation, which was enabled by copper/ligand complexes inclusion (0.25 wt% relative to solvent) zinc oxide (ZnO) nanocrystals activated UV light. This approach tested for poly(methyl methacrylate) (PMMA) prepared atom transfer radical polymerization (ATRP); effects solvent polarity activity ligands were investigated. Unexpectedly, a low-activity Cu-complex with 2,2'-bipyridyne ligand, combination low-polarity solvent, 1,2,4-trichlorobenzene, relatively high yields less than 1 h at 150 °C. Higher ATRP tris(2-pyridylmethyl)amine (TPMA) N,N,N',N'',N''-pentamethyldiethylenetriamine (PMDETA) ligands, efficient, associated their decomposition and/or excessive formation radicals premature termination chain ends. The presented facile designed be used even partially aerated reactors, opening new avenues depolymerization.
