Nitroxide-Mediated Radical Polymerization of Styrene Initiated from the Surface of Titanium Oxide Nanoparticles
Titanium dioxide (TiO2) nanoparticles, with an average size of about 45 nm, were encapsulated by polystyrene using in situ nitroxide mediated radical polymerization in the presence of 3-aminopropyl triethoxy silane (APTES) as a coupling agent and 2, 2, 6, 6-tetramethylpiperidinyl-1-oxy as a initiator. First, the initiator for NMRP was covalently bonded onto the surface of Titanium dioxide na...
متن کاملInhibition of arenavirus infection by thiuram and aromatic disulfides.
A selected group of aromatic disulfides, thiuram disulfides and thiosulfones, provided by the National Cancer Institute, were evaluated in vitro for their inhibitory activity against Junin virus (JUNV), the causative agent of Argentine hemorrhagic fever. The aromatic disulfides NSC4492 and NSC71033 and the thiuram disulfide NSC14560 were, respectively, the more potent virucidal and antiviral ag...

متن کاملDispersion polymerization of styrene and methyl methacrylate initiated by macromonomeric azoinitiator
The free radical dispersion polymerization of styrene (St) and methyl methacrylate (MMA) initiated by poly(oxyethylene) (PEO) macroazoinimer (MIM-400) in water/ethanol, was investigated at three different temperatures (50, 60 and 80 8C) for seven polymerization times (3, 6, 9, 12, 24, 36 and 48 h). PStPEO and PMMA-PEO networks were obtained. In each case, polymer gel fractions depend on the pol...
متن کاملSurface-Initiated Anionic Polymerization of Styrene by Means of Self-Assembled Monolayers
A synthetic concept of preparing dense polymer brushes on planar surfaces is described, in which a self-assembled monolayer (SAM) of biphenyllithium moieties on gold substrates is used to initiate anionic polymerization of styrene. The thickness of the resulting dry polystyrene brush, as estimated by ellipsometry and atomic force microscopy (AFM), is 18 ( 0.2 nm. These techniques also reveal a ...
