A number of processes are available: condensation-, interfacial-, suspensionand emulsion-polymerization. Suspension and emulsion polymerization are the preferred methods for the commercial production of polymer microsphere carrier particles and reference/standard particles for calibration of scientific instruments. In general, emulsion polymerization produces a smaller particle size and a narro...

polybutadiene nanoparticles were synthesized via batch emulsion polymerization of butadiene in the presence of potassium persulfate, disproportionate rosinate potassium cation and t-dodecyl mercaptane as initiator, emulsifier and chain transfer agent, respectively. polymerization reaction was performed at different temperatures (60, 70 and 80 °c). conversion was measured at the various time int...

The focus of this work was to improve the aqueous emulsion polymerization of a highly water-insoluble monomer derived from plant oil, acrylated methyl oleate. Conventional emulsion polymerization requires excessive amounts of surfactant and long reaction time. Miniemulsion polymerization improved the polymerization significantly. Only a fraction of the surfactant and reaction time that was nece...

‎(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...

Emulsion polymerization reactions constitute complex, nonequilibrium systems in which there is strong interaction between polymers, monomers, and the colloidal structures that mediate the reactions. A novel and general method was sought to monitor emulsion polymerization reactions. Instrumentation and methods were hence developed here to achieve, for the first time, simultaneous monitoring of t...

A new approach to synthesis of cross-linked colloidosomes (microcapsules with a shell from colloidal particles) was developed on the basis of a peroxidized Pickering emulsion (an emulsion stabilized exclusively by peroxidized colloidal particles). Peroxidized latex particles were employed to ensure formation of Pickering emulsion. Free radical polymerization was used to convert droplets of a pe...

INTRODUCTION Emulsion polymerization yielding polymer latexes, is carried out on a vast scale. The use of water as a dispersion medium offers a unique combination of features, such as effective heat transfer, effective stabilization of polymer particles by surfactants, and environmental friendliness. By contrast to polymerization in solution or in the bulk, in emulsion polymerization a large po...

Emulsion polymerization is one of the most important and versatile polymerization processes. About 10 million tonnes of polymer latices are produced annually for a variety of applications, such as coatings and paints. A key step in most applications is film formation upon evaporation of the dispersing medium, rendering aqueous dispersions particularly environmentally benign. Polymer dispersions...

Carbazole was oxidized by benzoyl peroxide in presence of p-toluenesulfonic acid to polycarbazole salt at room temperature for the first time. Polycarbazole salts were synthesized via solution and emulsion polymerization pathways. Polycarbazole bases were prepared by dedoping from polycarbazole salts. Formation of polycarbazoles was confirmed from infrared, electronic absorption and EDAX spectr...
