Grafting-from ATRP protocols using fluoropolymers as substrates are very often used. Actual positive proof that is the mechanism at work in grafting or occurred all scarce. This perspective article gives an overview of most relevant examples such well possible other mechanisms grafting.

The atom transfer radical polymerization (ATRP)-based continuous assembly of polymers (CAP) is a promising approach for fabricating thin film composite (TFC) membranes high flux. Here, we report the preparation CO2-selective TFC mixed matrix (MMMs) by incorporating different amounts [Cu24(m-bdc)24(EG)3(DMF)12] (EG3-MOP) nanocages (e.g., 2.5, 5, and 10 wt%) as CO2-philic fillers in poly(poly(eth...

Herein, mono- and disubstituted thioxanthones have been synthesized introduced as photosensitizers of iodonium salt for cationic free-radical photopolymerization epoxy an acrylate monomer, respectively. Photoinitiation activity these molecules was verified during processes performed upon exposure to visible LEDs 420, 455, 470 nm. The kinetics the followed using FT-IR spectroscopy. Moreover, dev...

atom transfer radical polymerization (atrp) of styrene was carried out at 105°c and a monte carlo simulation was employed to model the system. the variations of monomer conversion, the initiator concentration, average molecular weight, and molecular weight distribution were evaluated as the reaction proceeded. according to the results obtained, for similar reaction time, monomer conversion is h...

Addition of water to organic solvents enhances the rate atom transfer radical polymerization (ATRP). To understand origin this enhancement, effects H2O on redox properties [CuIITPMA]2+ and [BrCuIITPMA]+ (TPMA=tris(2-pyridylmethyl)amine), ATRP equilibrium (KATRP) activation (kact) constants methyl 2-bromopropionate by [CuITPMA]+ were investigated in CH3CN, DMF DMSO their mixtures with acrylate (...

A visible light-cleavable polymer is synthesised to overcome the limitations of UV-sensitive polymers. Photocleavable BODIPY functionalized with an ATRP initiator and alkyne was used to obtain an amphiphilic block copolymer by conducting the click reaction and polymerization simultaneously. Micellar assembly of the polymer was disintegrated under visible light irradiation with controlled releas...

A novel copper(II) complex has been developed in which the counter anion, acylphosphinate, serves as a visible light photoinitiator. This molecule is inactive in the dark but, upon visible light exposure, both CuAAC and ATRP reactions are readily and rapidly initiated.

Synthesis of poly(2,2,2-trifluoroethyl methacrylate) by supported ATRP was investigated in supercritical carbon dioxide using a copper salt ligated to a polymeric ligand immobilised onto silica; after polymerisation, fluorinated polymers with well defined molecular weight and low polydispersity were obtained.

Electrospun nanofiber membranes surface functionalized with 3D nanolayers through ATRP provide adsorption capacities over 50-times higher than current commercial membrane adsorption systems and over 12-times higher than packed bed resins; additionally, the adsorption kinetics remain 10-times faster than packed bed resins and have over 15-times higher permeance.

Poly(p-phenylenevinylene)s (PPVs) with single reactive end groups have been prepared with high molecular weights, narrow polydispersities (ĐM) and excellent end functionality (f). PPVs functionalised with α-bromoester end groups are effective macroinitiators in the atom transfer radical polymerisation (ATRP) of methyl methacrylate (MMA).
