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...
متن کاملSynthesis 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...
متن کاملPickering 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...
متن کاملThE EFFECT OF METAKOLIN, MICROSILICA AND NANOSILICA ON THE MECHANICAL PROPERTIES AND MICROSTRUCTURE OF CEMENT MORTAR
Different mineral admixtures of Indian metakaolin, Iranian silica fume and nanosilica were used to produce high performance mortars. Two different sands types with grain size of 0.015-4mm were mixed with type II Portland cement, polycarboxylate superplasticizer,mineral admixture with 650kg/m3 cement content and water/cement ratio of 0.35. Different amount of cement was replaced by metakaolin or...
متن کاملStudy of structure and thermal properties of styrene-butylacrylate copolymer with OMMT nanocomposite emulsions
(St-co-BA) polymer through montmorillonite (MMT) nanocomposite emulsion is prepared by in situ intercalative emulsion polymerization of styrene (St), butyl acrylate (BA) in the presence of organic modified montmorillonite (OMMT) with different OMMT contents (0, 0.5, 1.0, 1.5, and 2.0 wt%). The synthetic compounds are characterized by FTIR, XRD. The nanocomposite emulsions are characterize...
