Synthesis and characterization of polystyrene-graphite nanocomposites via surface RAFT-mediated miniemulsion polymerization
Graphite oxide (GO) was prepared and immobilized with dodecyl isobutyric acid trithiocarbonate (DIBTC) reversible addition-fragmentation chain transfer (RAFT) agent. The hydroxyl groups of GO were attached to the DIBTC ...
Comparative study of classical surfactants and polymerizable surfactants (surfmers) in the reversible addition-fragmentation chain transfer mediated miniemulsion polymerization of styrene and methyl methacrylate
Cationic and anionic amphiphilic monomers (surfmers) were synthesized and used to stabilize particles in miniemulsion polymerization. A comparative study of classical cationic and anionic surfactants and the two surfmers ...
Use of acrylic based surfmers for the preparation of exfoliated polystyrene-clay nanocomposites
Two polymerizable cationic surfactants, (11-acryloyloxyundecyl)dimethyl(2-hydroxyethyl)ammonium bromide (hydroxyethyl surfmer) and (11-acryloyloxyundecyl)dimethylethylammonium bromide (ethyl surfmer), were used for the ...
Use of the surfmer 11-(methacryloyloxy) undecanylsulfate MET as a comonomer in polystyrene and poly(methyl methacrylate)
The polymerizable surfactant sodium 11-(methacryloyloxy) undecanylsulfate (MET) has been synthesized with high purity, and its thermal stability and phase transitions have been studied by thermo gravimetric analysis (TGA) ...
Change in physico-chemical properties of PMMA and PS by copolymerization with an anionic amphiphilic comonomer: Sodium 11-(methacryloyloxy) undecanylsulfate (MET)
Sodium 11-(methacryloyloxy) undecanylsulfate (MET) monomer units were incorporated in polystyrene (PS) and poly(methyl methacrylate) (PMMA) by free radical copolymerization in solution with styrene and methyl methacrylate, ...
