The coordination polymerization of ethylene in water as a reaction medium was studied. Rubbery amorphous branched polyethylene was obtained when a known cationic diimine-substituted methyl complex was employed as a catalyst precursor. High rates of up to 900 TOh(-1) (turnover frequency) were observed. In contrast to solution polymerization in an organic solvent, the rate of suspension polymeriz...

Organic–inorganic hybrid materials have attracted much interest because of their novel and specific characteristics. One method to obtain these materials is in situ polymerization through free-radical polymerization. In this study, styrene monomers were covalently linked to silica (SiO2) using the suspension polymerization technique. In the reaction process, benzoyl peroxide was used as an init...

Ischemia causes desquamation of proximal tubular epithelial cells leading to acute renal failure. However, the molecular mechanisms underlying the detachment of proximal tubule cells remain unknown. In this study, we reported that ATP depletion resulted in actin polymerization, a shift of filamentous actin from web-like structure to fragmented parallel stress fibers, followed by a reduction of ...

This work demonstrates the use of canola oil as a biologically compatible solvent for thiol–ene driven suspension polymerization that effectively creates micron-sized particles.

Polyaniline (PANI) nanocomposite has been successfully prepared in aqueousmedia by the chemical polymerization of aniline with ammonium peroxydisulphateas an initiator in the presence of a steric stabilizer such as sodium dodecylbenzenesulfonate(DBSNa), Poly(vinyl pyrrolidone) (PVP), poly(vinyl alcohol)(PVA), poly(ethylene glycol) (PEG) and hydroxypropylcellulose (HPC). Thechemical structure, m...

This paper reports the synthesis of highly cross-linked polymers in supercritical CO2 (scCO2), both with and without the addition of a CO2-soluble diblock copolymer stabilizer. It was demonstrated that, under certain specific conditions, relatively uniform, nonporous poly(divinylbenzene) (PDVB) microspheres (1-5 μm diameter) can be generated in the absence of added stabilizers. The effects of c...
