Preparation of chitosan-g-polylactide graft copolymers via self-catalysis of phthaloylchitosan and their complexation with DNA

19-Feb-2010 | Li, Liu , Aibin, Shi , Shengrong, Guo , Yue’e, Fang , Song, Chen , ..., Reactive and Functional Polymers, 2010

The graft copolymer of chitosan-g-polylactide (CS-g-PLA) was synthesized successfully through ring-opening polymerization of lactide onto phthaloyl-protected chitosan by a self-catalysis strategy. After graft copolymerization, the phthaloyl groups were deprotected to regenerate free amino groups ...

Dual-stimuli sensitive composites based on multi-walled carbon nanotubes and poly(N,N-diethylacrylamide-co-acrylic acid) hydrogels

16-Feb-2010 | Hongliang, Liu , Mingzhu, Liu , Lijing, Zhang , Liwei, Ma , Jun, Chen , ..., Reactive and Functional Polymers, 2010

A strategy to prepare dual-stimuli sensitive poly(N,N-diethylacrylamide-co-acrylic acid) composite hydrogels has been demonstrated. Multi-walled carbon nanotubes (MWCNTs) functionalized with vinyl groups were copolymerized with N,N-diethylacrylamide (DEA), acrylic acid (AA) and ...

Solvent Impregnated Resins (SIRs) -Methods of Preparation and Their Applications

10-Feb-2010 | Nalan, Kabay , Jose Luis, Cortina , Andrzej, Trochimczuk , Michael, Streat, Reactive and Functional Polymers, 2010

Interest in the development of solvent impregnated resins (SIRs) and their applications for the separation of metal ions and organic compounds from water in the form of a hybrid polymeric adsorbent material has intensified over the past thirty years. SIRs are particulate adsorbers that possess a ...

Photocatalytic Degradation of Methyl Orange Using Polythiophene/Titanium Dioxide Composites

05-Feb-2010 | Yunfeng, Zhu , Shoubin, Xu , Yi, Dan, Reactive and Functional Polymers, 2010

Polythiophene/titanium dioxide (PT/TiO2) composites were prepared via in-situ chemical oxidative polymerization, and the obtained composites were characterized by X-ray photoelectron spectroscopy (XPS), ultraviolet-visible (UV-Vis) diffuse reflectance spectroscopy (DRS) and transmission electron ...

Synthesis and characterization of a new class of polymeric ligand exchangers for selective removal of arsenate from drinking water

05-Feb-2010 | Byungryul, An , Zengli, Fu , Zhong, Xiong , Dongye, Zhao , Arup K., SenGupta, Reactive and Functional Polymers, 2010

Six new chelating resins were prepared by functionalizing three commercially available XAD resins of various matrix properties, including XAD1180, XAD16 and XAD7HP. Two types of pyridinyl functional groups were loaded on these sorbents, one with two nitrogen donor atoms (2N) per functional group ...

High tensibility and pH-responsive swelling of nanocomposite hydrogels containing the positively chargeable 2-(dimethylamino)ethyl methacrylate monomer

30-Jan-2010 | Meina, Zhu , Lijun, Xiong , Tao, Wang , Xinxing, Liu , Chaoyang, Wang , ..., Reactive and Functional Polymers, 2010

Positively chargeable nanocomposite hydrogels (NC gels) were synthesized by in situ copolymerization of acrylamide (AM) and 2-(dimethylamino)ethyl methacrylate (DMAEMA) in an aqueous suspension of hectorite clay Laponite XLS. The stability of the Laponite suspension containing DMAEMA was ...

Defined Chitosan-based networks by C-6-Azide-alkyne “click” reaction

30-Jan-2010 | Giovanni, Zampano , Monica, Bertoldo , Francesco, Ciardelli, Reactive and Functional Polymers, 2010

Chitosan was converted to its –NH2 protected derivative by reacting with phtalic anhydride and then selectively functionalized with an azido group in C-6 position. Two different procedures were employed. The first was a “one pot” procedure and the second was a two steps reaction through the ...
