Preparation and characterization of crosslinked PMMA latex particles stabilized by grafted copolymer
Publikováno v:
Colloid & Polymer Science. 275:897-901
The preparation of polymethyl methacrylate lattices stabilized by polyhydroxystearic acid and crosslinked with ethylene glycol dimethylmethacrylate (EGDM) has been studied. Crosslinking is a new development in the synthesis of PMMA latex. The particl

A method is presented for the preparation of stable model dispersions of paramagnetic silica particles. A specially designed silane coupling agent containing Ni 2+ ions is grafted onto silica particles which are either commercially obtained or prepar

Viscous flow in dense packings of well-characterized, uncharged, monodisperse colloidal silica spheres with various stabilizing coatings has been studied as a function of time, pressure, and sphere size. Permeabilities scaled with measured radii are

Fairly monodisperse colloidal boehmite fibrils with a high aspect ratio were synthesized by hydrothermal treatment at 150°C of an acidified aqueous alkoxide solution, prepared by adding an aqueous HCl solution to an aluminum alkoxide precursor. The

Dispersions of colloidal boehmite (γ-AlOOH) rods (of controllable length) are prepared from alkoxide precursors. A polyisobutene grafting procedure leads to sterically stabilized dispersions. In the organophilic system (L ≈ 200 nm ± 50%; D ≈ 10

The preparation of monodispers crosslinked PMMA-latex by aqueous emulsion polymerization is described. Light scattering of these particles in benzene as a function of scattering angle showed structure formation at higher latex concentrations. The res

The synthesis of colloidal boehmite (AlOOH) is studied by heating basic aluminum chloride solutions under constant stirring. The temperature and Al2O3: Cl molar ratio influence the product morphology. Synthesis at 140°C generates highly fibrous poly

Preparation of alkane-grafted silica particles from aqueous commercial sols is described. The particles, grafted with C 18 or C 20 chains, are stable in nonpolar solvents and are suitable for small-angle neutron (SANS) and X-ray (SAXS) scattering stu

A single-step method to synthesize monodisperse metallic cobalt particles of diameter around 8 nm is described. The particles are sterically stabilized by modified polyisobutene and form stable ferrofluids in toluene. The core-shell cobalt spheres ha
