Semicrystalline microparticles of high molecular mass polyethylene can be prepared as aqueous dispersions by catalytic emulsion polymerization of ethylene with a mini-emulsified catalyst precursor (D$\rm{\frown}$D=salicylaldimine, L=pyridine). Stable polymer latexes are formed.

A simple formulation of a stable high internal phase emulsion of dicyclopentadiene which is cured by using properly selected ring opening metathesis polymerization initiators yields highly porous monolithic materials with paramount mechanical properties and the possibility of easy functionalisation.

Water-soluble nanographite was prepared by in situ emulsion polymerization using methacrylate as polymeric monomer. The dispersion stability and dispersion state of graphite particles were evaluated by UV-visible spectrophotometry and scanning electron microscopy, respectively. The water-soluble nanographite was then added into the water-based cutting fluid as lubricant additive. The lubricatio...

UNLABELLED The present study tested the hypothesis that intravascular micro bubbles generated by i.v. infusion of a 2 % dodecafluoropentane (DDFP) emulsion will enhance tissue denitrogenation during oxygen breathing. Eleven spontaneously breathing pentobarbital anesthetized pigs were studied. Six pigs were treated with 0.08 ml/kg of DDFP-emulsion infused over 30 min and five (control) pigs rece...

Herein we report the synthesis of highly cross-linked polymers based on divinylbenzene by heterogeneous polymerization in supercritical CO2 (scCO2). The polymers were isolated in the form of discrete microspheres (diameter = 1.5–5 lm) in good yields (F90%), in the absence of any stabilizers. In the presence of a CO2-soluble polymeric stabilizer, much smaller particles (diameter a0.5 lm) were fo...

In this work, gold-incorporated polyethylenedioxythiophene nanocomposite material has been synthesized chemically, employing reverse emulsion polymerization method. Infrared and Raman spectroscopic studies revealed that the polymerization of ethylenedioxythiophene leads to the formation of polymer polyethylenedioxythiophene incorporating gold nanoparticles. Scanning electron microscope studies ...

New non aqueous based microemulsion allows the delivery of storage sensitive personal care actives in conventional cream, lotion and gel. Griseofulvin is an antifungal antibiotic drug micro emulsion system as the basic formulation for investigation. The quantity of griseofulvin and the accumulation of anhydrous micro emulsions at various temperatures were analyzed with poor aqueous solubility. ...

The aim of the work is to present the main actual information on the preparation of polymers, derivatives of N-isopropylacrylamide, formed into microgels. The most often used comonomers, crosslinkers, and initiator systems are gathered herein. The known methods of emulsion polymerization and precipitation polymerization are also described, including the application of the surfactants, as well a...
