PSt-b-PU-b-PSt copolymers using tetraphenylethane-urethane macroinitiator through SARA ATRP

eXPRESS Polymer Letters, 2016
The course of supplemental activator and reducing agent (SARA) atom transfer radical polymerization (ATRP) has been presented in the presence of Cu0. The novelty of this work is that SARA ATRP has been used for the first time to synthesize polystyrene-b ...

Synthesis and characterization of amphiphilic nitroxide 1,1,3,3–tetraethylisoindoline–2–oxyl–5–sodium sulfonate (TEIOSNa)

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The synthesis and characterization of an amphiphilic nitroxide to be used as a controlling agent in a nitroxide‐mediated living radical polymerization in aqueous dispersion media is presented. In the first stage of nitroxide synthesis (phthalimide protection), two reaction methods were employed: traditional and microwave.

Biocatalytically Initiated Precipitation Atom Transfer Radical Polymerization (ATRP) as a Quantitative Method for Hemoglobin Detection in Biological Fluids [PDF]

Analytical Chemistry, 2019
The hemoglobin content of blood is an important health indicator, and the presence of microscopic amounts of hemoglobin in places where it normally does not occur, e.g. in blood plasma or in urine, is a sign of diseases such as hemolytic anemia or urinary tract infections.

Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.

Preparation and Characterization of Hyperbranched Polystyrene Nanocomposite Synthesized by Living Radical Polymerization and Solution Intercalation Method [PDF]

علوم و تکنولوژی پلیمر, 2013
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.
