Core-shell polymers in the particle size range 200–300 nm having a monodisperse distribution and opal color are prospective materials for coating applications. The emulsion polymerization of the core-shell was done using two monomers with significantly different refractive indices styrene for the hard monomers and butyl acrylate for the soft monomers. The feeding and aging time were varied, wit...

Ultrasonic transmission is a simple, non-destructive method to characterize turbid systems like e.g. emulsions or polymer dispersion. Here we use this technique for in-line monitoring of the miniemulsion polymerization of styrene. Either the ultrasound attenuation or the velocity signal provides a fingerprint characterizing the reaction process. During the reaction process the sound velocity in...

Carbon foams displaying hierarchical porosity and excellent surface areas of >1400 m²/g can be produced by the activation of macroporous poly(divinylbenzene). Poly(divinylbenzene) was synthesized from the polymerization of the continuous, but minority, phase of a simple high internal phase Pickering emulsion. By the addition of KOH, chemical activation of the materials is induced during carboni...

In present paper, dynamic behavior and control of a fluidized bed reactor for polyethylene production has been considered. A double active sites model for Ziegler-Natta catalysts is used for simulation of polymerization reaction. Hydrodynamic behavior of the bed is modeled using a two phase model including bubble and emulsion phases in which bubble phase has plug flow pattern with different...

Here, we prepared hydrophobic cryogel particles with monolithic supermacropores based on poly-trimethylolpropane trimethacrylate (pTrim) by combining the inverse Leidenfrost effect and cryo-polymerization technique. The adopting this method demonstrated separation of stabilized O/W emulsion surfactant. were characterized in terms macroscopic shape porous structure. It was found that had a narro...

Chair of Chemical Materials Science, Department of Chemistry, University of Konstanz, Germany Introduction Poly(p-phenylene vinylene) (PPV) and its derivatives are amongst the most widely studied class of conjugated polymers since the discovery of their electroluminescent properties in 1990. These polymers are studied for applications in numerous photonic devices such as organic solar cells, or...

Styrene Butadiene Rubbers (SBRs) are among the most useful synthetic rubbers which can be produced by two different methods of polymerization: emulsion and solution. These two polymerization methods lead to different final properties. In general, SBRs produced by the solution method (S-SBRs) have narrower Molecular Weight Distribution (MWD), higher content of cis-1,4 structure and lower glass t...
