Firstly, multi-walled carbon nanotubes (MWNTs) were modified with a furfuryl derivative RAFT agent by Diels-Alder reaction. The polymerization of styrene and maleic anhydride was carried out in the presence of functionalized MWNTs to afford MWNT/PSMA. The maleic anhydride ring located along the ...
Base-initiated polymaleic anhydride is substantially decarboxylated, and the resulting polymer has anhydride and carboxyl groups. Elemental analyses and 1 H-NMR spectra obtained on the pyridine-initiated polymer and its methyl ester refute both the cis -poly(vinylene ketoanhydride) structure suggested ...
The functionalized multiwall carbon nanotubes (MWNTs) have been prepared by free radical reaction with maleic acid and maleic anhydride. The functionalized MWNT was further blended with poly(dimethylsiloxane) (PDMS) based Poly(urea-urethane) (PUU). Both maleic acid modified MWNT (Maa-g-MWNT) and...

Radical copolymerization of styrene (St) and maleic anhydride (Man) was performed in supercritical carbon dioxide (SC CO2) at 5080 °C with 2,2'-azoisobutyronitrile as the initiator. A novel, ultrahigh molecular mass StMan alternative copolymers (Mw > 106) has been synthesized. The NMR spectra...
The aim of this work was to modify poly lactic acid (PLA) via free radical grafting with maleic anhydride (MA) by using supercritical carbon dioxide (SCCO). Benzoyl peroxide (BPO) was used as an initiator. The solubility of MA in SCCOwas first determ...
Silver nanoparticles on the surface of carbon nanotubes functionalized with maleic anhydride through plasmainduced grafting process, named CNTs-MA-Ag, were synthesized. Effects of CNTs-MA-Ag as conductive additives on the performance of LiFePO4 polyanion-based lithium-ion batteries was studied. X-ray...
