Complex multiblock bottle-brush architectures by RAFT polymerization

15-Jan-2018 | Andrew Kerr; Matthias Hartlieb; Joaquin Sanchis; Timothy Smith; Sébastien Perrier, Chemical Communication, 2018

The combination of the reversible addition fragmentation chain transfer (RAFT) polymerization R-group grafting from approach and RAFT one-pot acrylamide multiblock methodology is used to synthesise complex bottle-brush architectures. This is demonstrated for block copolymer grafted side chains ...

Templating polyacrylamide hydrogel for interconnected microstructure and improved performance

11-Jan-2018 | Maria Bassil, Georges El Haj Moussa, Mario El Tahchi, Journal of Applied Polymer Science, 2018

ABSTRACT In this study, the pressure and temperature are monitored during acrylamide polymerization and their effects on the mechanical properties and swelling of the resulting hydrogel are investigated. The polymerization kinetic and network formation mechanism are correlated to the ...

Structure and topography of thermally reduced graphene oxide reinforced poly(vinyl alcohol‐g‐acrylonitrile) films and study of their mechanical and electrical behavior

11-Jan-2018 | Sangeeta Maravi, Jaya Bajpai, Anil K. Bajpai, Polymer Composites, 2018

Thermally reduced graphene oxide (TRGO) reinforced poly(vinyl alcohol‐g‐acrylonitrile) (PVA‐g‐PAN) films were prepared by carrying out graft co‐polymerization of acrylonitrile onto poly(vinyl alcohol) in a thermally and mechanically stabilized and reduced suspension of GO using potassium ...

Synthesis of (meth)acrylamide-based glycomonomers using renewable resources and their polymerization in aqueous systems

10-Jan-2018 | Azis Adharis; Dennis Vesper; Nick Koning; Katja Loos, Green Chemistry, 2018

In this work, we present the kinetically-controlled enzymatic synthesis of novel glycosyl-(meth)acrylamide monomers using β-glucosidase. Cellobiose served as the glycosyl donor in the enzyme catalyzed transglycosylation reaction and hydroxyl-alkyl (meth)acrylamides as the glycosyl acceptor. After ...

Rapid Capture and Release of Nucleic Acids through a Reversible Photo‐cycloaddition Reaction in the Psoralen‐functionalized Hydrogel

08-Jan-2018 | Yizhe Zhang, Peggy Chan, Amy Herr, Angewandte Chemie International Edition, 2018

Reversible immobilization of DNA and RNA is of great interest to researchers who seek to manipulate DNA or RNA in applications such as microarrays, DNA hydrogels and gene therapeutics. However, there is no existing system that can rapidly capture and release intact nucleic acids. To meet this ...

Influence of sodium dodecyl sulfate on the kinetics and control of RAFT/MADIX polymerization of acrylamide

04-Jan-2018 | Cécile Barthet, James Wilson, Arnaud Cadix, Mathias Destarac, Christophe Chassenieux, Simon Harrisson, Journal of Polymer Science Part A: Polymer Chemistry, 2018

ABSTRACT Aqueous radical polymerizations of acrylamide were conducted in the presence of varying concentrations of sodium dodecyl sulfate (SDS) and two xanthate reversible addition‐fragmentation chain transfer (RAFT) agents: the small, hydrophobic Rhodixan A1 and the oligomeric, amphiphilic ...

Preparation and performance of novel temperature‐resistant thickening agent

27-Dec-2017 | Siming Yan, Jun Tang, Shengdong Yan, Yongji Wang, Jinjing Han, Suqing Shi, Polymers for Advanced Technologies, 2017

Abstract In this article, a novel kind of temperature‐resistant thickening agent (LK) was copolymerized with acrylamide, acrylic acid, sodium p‐styrenesulfonate, and dimethyl diallyl ammonium chloride via free radical copolymerization. The polymerization conditions were optimized by the ...

Synthesis of Amphiphilic Block Copolymers Based on SKA by RAFT Polymerization

21-Dec-2017 | Xiaoqian Yu, Marie‐Theres Picker, Martin Schneider, Artjom Herberg, Sagrario Pascual, Laurent Fontaine, Dirk Kuckling, Macromolecular Chemistry and Physics, 2017

Abstract Temperature‐sensitive amphiphilic block copolymers of 2,2‐dimethyl‐1,3‐dioxolan‐4‐yl‐methyl acrylate (solketal acrylate, SKA) and N‐isopropyl acrylamide (NIPAAm) have been prepared via reversible addition‐fragmentation chain transfer radical polymerization (RAFT). A kinetics study of ...
