Control of Poly(styrene) Particles Size by In-Situ Polymerization

Synthesis of Silica/Polystyrene Nanocomposite Particles by Miniemulsion Polymerization

Miniemulsion polymerization is one of heterogeneous polymerization method that can be effectively used to synthesis of various novel organic-inorganic nanocomposite particles. This method can provide opportunity of good incorporation between the polymer and inorganic phases in the formed submicrometer-sized particles. In this article, we report preparation polystyrene/silica nanocomposite p...

synthesis of silica/polystyrene nanocomposite particles by miniemulsion polymerization

The morphological control of anisotropic polystyrene/silica hybrid particles prepared by radiation miniemulsion polymerization.

Novel anisotropic hybrid particles with various morphologies have been synthesized by radiation miniemulsion polymerization for the first time.

preparation of polystyrene nanocomposite by in situ atom transfer radical polymerization: study of polymerization kinetics in the presence of clay

styrene nanocomposites were synthesized by in-situ atom transfer radical polymerization at 110oc. the variations of monomer conversion and the linearity of semilogarithmic kinetic plot, some signs of living polymerizationand constant radical concentration in the reaction medium, were revealed by gas chromatography technique (gc). according to the gel permeation chromatography (gpc) results, the...

Size and density of polystyrene particles measure by ultracentrifugation.

A material currently in use (1) for calibration of electron magnification is a polystyrene latex, characterized by a remarkably high degree of particle uniformity with respect to size and shape. The particles, spherical in shape and stable in water suspension, are in a range suitable not only for electron micrography but for independent determinations of size by sedimentation velocity, viscosit...
