Here we describe the combined process of surface modification with electrochemical atom transfer radical polymerization (e-ATRP) initiated from the surface of a modified gold-electrode in a pure aqueous solution without any additional supporting electrolyte. This approach allows for a very controlled growth of the polymer chains leading towards a steady increase in film thickness. Electrochemic...

a copolymer of styrene and methyl styrene was synthesized by nitroxide - mediated “living” free radical polymerization )nmp). n-bromosuccinimide was used as a brominating agent to obtain a copolymer with bromine as its end group. this brominated copolymer was used as macro initiators for atom transfer  radical  polymerization  (atrp).  chemical  modifcation  of  the  clay  and transformation of...

Abstract Photoinduced initiators for continuous activator regeneration atom transfer radical polymerization (PICAR ATRP) using sodium pyruvate and blue light ( λ max = 456 nm) is reported. Water‐soluble oligo(ethylene oxide) methyl ether methacrylate (OEOMA 500 ) was polymerized under biologically relevant conditions. Polymerizations were conducted with 1000 ppm (with respect to the monomer) co...

polyacrylontrile synthesis, via atom transfer radical polymerization, is studied in various initiator concentrations, transitional metal catalyst and different concentrations of cubr2. the variations of monomer conversion and the lin-earity of semi-logarithmic kinetic profile which is the evidence of living polymerization and constant radical concentration in the reaction medium, were revealed ...

In current study,a hydrogel based on biocompatible polymerwas prepared. The functionalization of polyvinyl alcohol (PVA)with epichlorohydrin(ECH) to produce epichlorohydrin-g-polyvinyl alcohol (PVA/ECH) as a suitable macroinitiator for atom transfer radical polymerization (ATRP) reaction was investigated.ThenN-vinyl pyrrolidone (NVP) waspolymerized on the surface of macroinitiatorin presence of...

Electrochemically mediated atom transfer radical polymerization (eATRP) of styrene was studied in detail by using CuBr2/TPMA (TPMA = tris(2-pyridylmethyl)amine) as a catalyst. Redox properties various Cu(II) species were investigated CH3CN, dimethylformamide (DMF), and dimethyl sulfoxide (DMSO) both the absence presence 50% (v/v) styrene. This investigation together with preliminary eATRP exper...

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...
