The benefits of miniemulsion and emulsion polymerization are combined in a seeded emulsion polymerization process with functional seed particles synthesized by miniemulsion polymerization. A systematic study on the influence of different reaction parameters on the reaction pathway is conducted, including variations of the amount of monomer fed, the ratio of initiator to monomer and the choice o...

Superparamagnetic nanorings of polystyrene/Fe3O4 composite were synthesized by miniemulsion polymerization. The nanoring structure was characterized by using transmission electron microscopy, scanning electron microscopy, and atomic force microscopy. The results of X-ray diffraction identified the magnetic constituent of as-synthesized composite nanorings as Fe3O4. The magnetization measurement...

kinetics of radical polymerizations of waterborne alkyd/acrylic hybrid resin via batch mini-emulsion technique was studied using redox initiators (tbhp/fe2+/edta/asac  and  tbhp/fe2+/edta/sfs) at relatively low temperatures and thermal initiators (bpo, kps and aibn) at higher temperatures to seek the most suitable initiator system. at the end of all reactions the unreacted monomer content was r...

Photoinitiated thiol–ene polymerization was performed in bulk and miniemulsion. We show that the compartmentalization of reaction inside nanodroplets led to faster kinetics yielded polymers with higher molecular weight.

Cellulose nanocrystals (CNCs) show promise for enhancing properties of waterborne latexes and coatings. Miniemulsion polymerization is a promising route to obtaining well-controlled latex distributions sufficient encapsulate CNCs in the monomer phase. Here, we demonstrate first miniemulsion resulting encapsulation that incorporates costabilizer, water soluble initiator, comonomer mixtures, aspe...

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...

Miniemulsion polymerization technique has been used extensively for preparing small sized uniform particles of polymers, core-shell polymer particles, hybrid particles and encapsulation of liquid core. The technique has achieved limited success in the area of uniform core shell structure with liquid as core, as it requires matching of strict thermodynamic and kinetic factors. The interfacial te...

A novel Y-shaped macromonomer based on poly[(dimethylamino)ethyl methacrylate] (PDMAEMA) with a narrow molecular weight distribution was synthesized via oxyanion-initiated polymerization in which a potassium alcoholate of trimethylol propane allyl ether (2K-TMPAE) was used as a difunctional initiator. For the miniemulsion polymerization of styrene, this macromonomer acted well both as a comonom...

Waterborne isocyanate-free grafted poly(hydroxy urethane)-poly(butyl methacrylate) hybrid dispersions were synthesized by miniemulsion polymerization. Grafting was induced including methacrylate functionalities in the urethane) and controlled degree of functionalization. It is shown that grafting enabled a fine tuning mechanical properties PHU containing hybrids.
