pickering emulsion polymerization of styrene-co-butyl acrylate nanoparticles by using cloisite na+ as surfactant

Pickering Emulsion Polymerization of Styrene-co-butyl Acrylate Nanoparticles by Using Cloisite Na+ as Surfactant

Cloisite Na+was used as a solid surfactant (stabilizer) in Pickering emulsion polymerization of styrene-co-butyl acrylate in presence of oil soluble initiator, azobisisobutyronitrile (AIBN) and water soluble initiator, potassium persulfate (KPS). Fourier transform infrared (FTIR) spectrum approved the corporation of Cloisite Na+ layers within the polymer matrix. Effect of clay content was a...

High Solid Contents Copoly (Styrene/Butyl Acrylate)-Cloisite 30B Nanocomposites

Higher solid contents (20 % and 40 %) nanocomposites of poly (styrene-co-butyl acrylate) including higher content of Cloisite 30B (7 wt% and 10 wt %) were prepared via miniemulsion polymerization. Stability of the final latexes proved outstanding combination of polymerization procedure and surfactants. Morphological studies revealed by TEM, SAX and XRD showed three structures of core-shell, arm...

Synthesis and Properties of Poly(styrene-co-butyl Acrylate) Particles via Microwave-aided Emulsion Copolymerization

As a peculiar and powerful energy source, microwave has been widely applied to optimize and accelerate the chemical reaction. As an alternative to conventional heating techniques, microwave irradiation provides an effective, selective and fast synthetic method by heating the molecules directly through the interaction between the microwave energy and molecular dipole moments of the monomers. Thi...

Advanced Core-Shell Composite Nanoparticles Through Pickering Emulsion Polymerization

Multiblock Copolymers of Styrene and Butyl Acrylate via Polytrithiocarbonate-Mediated RAFT Polymerization

When linear polytrithiocarbonates as Reversible Addition-Fragmentation chain Transfer (RAFT) agents are employed in a radical polymerization, the resulting macromolecules consist of several homogeneous polymer blocks, interconnected by the functional groups of the respective RAFT agent. Via a second polymerization with another monomer, multiblock copolymers—polymers with alternating segments of...
