Preparation of Polystyrene-Polyimide Particles by Dispersion Polymerization of Styrene Using Poly(amic acid) as a Stabilizer

Dispersion Polymerization of Polystyrene Particles Using Alcohol as Reaction Medium

In this study, monodisperse polystyrene nanospheres were prepared by dispersion polymerization using alcohol as reaction medium to prepare colloidal clusters of the latex beads. Polyvinylpyrrolidone (PVP) and 2-(methacryloyloxy)ethyltrimethylammonium chloride (MTC) were used as dispersion stabilizer and comonomer, respectively. The particle size could be controlled by adjusting the reactant com...

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...

Preparation of Inert Polystyrene Latex Particles as MicroRNA Delivery Vectors by Surfactant-Free RAFT Emulsion Polymerization.

We present the preparation of 11 nm polyacrylamide-stabilized polystyrene latex particles for conjugation to a microRNA model by surfactant-free RAFT emulsion polymerization. Our synthetic strategy involved the preparation of amphiphilic polyacrylamide-block-polystyrene copolymers, which were able to self-assemble into polymeric micelles and "grow" into polystyrene latex particles. The surface ...

Preparation of monodisperse PMMA microspheres in nonpolar solvents by dispersion polymerization with a macromonomeric stabilizer

Recently, monodisperse polymer colloids have found a new application as templates for photonic crystals [1]. At a sufficiently high volume fraction and low polydispersity, spherical particles will self assemble into a facecentered cubic lattice, even in the absence of attractive interparticle forces [2]. Such structures can diffract light if the wavelength is comparable to the spacing between t...
