Study Results from S. Chakraborty and Colleagues Broaden Understanding of Styrenes (Synthesis of Magnetic Polystyrene Nanoparticles Using Amphiphilic Ionic Liquid Stabilized RAFT Mediated Miniemulsion Polymerization)

By a News Reporter-Staff News Editor at Science Letter -- New research on Styrenes is the subject of a report. According to news reporting out of Riyadh, Saudi Arabia, by NewsRx editors, research stated, "Imidazole based amphiphilic ionic liquids (ILs) were used as surfactants in miniemulsion polymerization (MEP) of styrene using a free radical process as well as reversible addition-fragmentation chain transfer (RAFT). Monodisperse polystyrene (PS) nanoparticles were obtained, demonstrating the efficiency of the amphiphilic IL as surfactant in MEP."

Our news journalists obtained a quote from the research, "IL stabilized miniemulsion was furthermore used to prepare polystyrene based magnetic nanoparticles (MNP). A large increase of the possible MNP content associated with very good colloidal stability was achieved using IL stabilized RAFT mediated MEP where a carboxyl functionalized chain transfer agent (CTA) was applied, allowing interaction with the MNP surface. The molecular weight and dispersity index of polystyrene, the content of MNP, and the morphologies of the hybrid nanoparticles were controlled by proper optimization of the concentration of initiator and CTA. The materials have been analyzed by NMR, GPC, DLS, SEM, TEM, and TGA."

According to the news editors, the research concluded: "Finally, the magnetic properties of the materials were determined by vibrating sample magnetometer (VSM) analysis."
