Predictive Tool for Design and Analysis of ARGET ATRP Grafting Reactions
Macromolecules, 2017Solving a comprehensive, yet simple, reaction model for describing the activators regenerated by electron transfer (ARGET)–atom transfer radical polymerization (ATRP) reaction cascade, we show that the molar ratios of transition metal catalyst to initiator and reducing agent to catalyst are critical parameters in the ARGET ATRP mechanism, with optimal ...

Numerical simulation and parametric study of solution ARGET ATRP of styrene
Computational Materials Science, 2016Abstract This paper uses an ARGET ATRP mathematical modeling to study the solution polymerization of styrene. Differently from previous published works, a detailed parametric study was performed in order to verify how chemical species behave throughout the polymerization process and to provide a numerical tool for analysis, optimization and process ...

Postmodification of PS-b-P4VP Diblock Copolymer Membranes by ARGET ATRP
Langmuir, 2014The surfaces of polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) diblock copolymer membranes were modified in order to obtain polymer brushes by using surface-initiated activators regenerated by electron transfer atom transfer radical polymerization (ARGET ATRP).

A ratiometric electrochemical biosensor based on ARGET ATRP for detection of HER2 gene
TalantaHuman epidermal growth factor receptor 2 (HER2), a common proto-oncogene, is overexpressed in a subset of breast cancer patients. It is essential to track HER2 expression for early breast cancer diagnosis. Herein, a ratiometric electrochemical biosensor for detection of HER2 based on activators generated by electron transfer for atom transfer radical ...

Macromolecular Rapid Communications, 2012
AbstractHyperbranched polymers with multiple alkyl bromide peripheral groups were synthesized by the copolymerization of styrene with ethylene glycol dimethacrylate (2.5, 5.0, 7.5, or 10.0 mol% relative to styrene) in the presence of CBr4 (10–20‐fold excess vs. the radical initiator).

Polycationic Nanoparticles for siRNA Delivery: Comparing ARGET ATRP and UV-Initiated Formulations
ACS Nano, 2014In this work, we develop and evaluate polycationic nanoparticles for the delivery of small interfering RNA (siRNA). Delivery remains a major challenge for translating siRNA to the clinic, and overcoming the delivery challenge requires effective siRNA delivery vehicles that meet the demands of the specific delivery strategy.

Mini Monomer Encapsulated Emulsion Polymerization of PMMA Using Aqueous ARGET ATRP
ACS Macro Letters, 2018A new emulsion polymerization based on Activators Regenerated by Electron Transfer Atom Transfer Radical Polymerization (ARGET ATRP) has been developed to produce poly(methyl methacrylate) (PMMA). The critical components of single-pot synthesis via a mini Monomer Encapsulated ARGET ATRP emulsion polymerization will be discussed. In this method, monomer

A novel block copolymer with excellent amphiphobicity synthesized via ARGET ATRP
Journal of Polymer Science Part A: Polymer Chemistry, 2016The poly(methyl methacrylate)-b-poly(2-[[[[2-(perfluorohexyl)]-sulfonyl]-amino]ehthyl] methacrylate) (PMMA-b-PC6SMA) copolymers were successfully synthesized for the first time using activator regenerated by electron transfer atom transfer radical polymerization (ARGET ATRP) method. Under optimized reaction conditions, the degree of polymerization (DP)

Structure and Properties of Silk Grafted with 2-Hydroxyethyl Methacrylate by ARGET ATRP
Advanced Materials Research, 2012In this work, silk was reacted with 2-bromoisobutyryl bromide to obtain silk macroinitiator for activators regenerated by electron transfer for atom transfer radical polymerization (ARGET ATRP). Silk macroinitiator was grafted with 2-hydroxyethyl methacrylate (HEMA) via ARGET ATRP method to produce grafted silk in water aqueous.
