Poly(methyl methacrylate- co-ethylene glycol dimethacrylate- co-vinylbenzyl chloride) microsphere was prepared by dispersion polymerization, initiated by light using water/ethanol mixture. The sulfonated hypercrosslinked (HXL) polymer resin was synthesized via three stages, namely, precursor synthesis (photoinitiated dispersion polymerization), post-polymerization after hypercrosslinking reaction, and post-polymerization before hypercrosslinking reaction. The optimized precursor was functionalized before the hypercrosslinking reaction to investigate its ion-exchange capacity, specific surface area (SSA), morphology, and thermal stability. Post-polymerization after hypercrosslinking reaction showed that the chlorine content and SSA are higher than post-polymerization before hypercrosslinking reaction. HXL reaction took place using Friedel–Crafts alkylation with the aid of FeCl3 catalyst. Lewis acid (FeCl3) also played a significant role which contributed to high SSA of the HXL polymer. The particles produced from photoinitiated dispersion polymerization have advantages and could be used in solid-phase extraction, drug delivery, and high-performance liquid chromatography.

ABSTRACT1-Phenyl-3-naphthyl-5-((dimethylamino)phenyl)-2-pyrazoline with different diameters of 40 - 190 nm were prepared by the reprecipitation method and polymerized with poly(methyl methacrylate-co-ethylene glycol dimethacrylate) using cationic surfactants for full color electronic paper, which is expected to substitute for the future display. The electronic ink particles of pyrazoline organic nanoparticles polymerized by poly(methylmethacrylate-co-ethylene glycol dimethacrylate) were prepared and monodispersed successfully in aqueous alcohol medium. The size of mono-dispersed electronic ink particles is from 160 to 550 nm. The ink particle size was found to decrease with increasing concentration of the surfactant. The effect of surfactant was significant. The appropriate additions of surfactants result in an increase in electrophoretic mobility. The electrophoretic mobility of the resulting electronic inks was −7.5 to −3.6 × 10−5 cm2/ V·s in the presence of surfactants.

AbstractPoly(methyl methacrylate-acrylic acid-ethylene glycol dimethacrylate) copolymer particles abbreviated as P(MMA-AA-EGDM) copolymer particles were prepared by soap-free emulsion copolymerization. The concentration of carboxyl group on/near the surface of particles increased with the increase in acrylic acid (AA) content in the recipe. The carboxyl groups were reacted with amine nucleophiles such ethylene diamine and 1,6-diaminohexane through preactivation with dicyclohexyl carbodiimide as a coupling agent. The modified particles were characterized by electron micrographs and FTIR spectral analysis. Adsorption behaviours of some biomolecules were measured to have idea about=-0 the polarity of the particles surface
