Resumen o descripción

The preparation of magnetic latexes using styrene monomer was carried out via the miniemulsion polymerization technique. Magnetite

(Fe3O4), with an average size of 12 nmwas used as magnetic particles. An organic phasewas prepared dispersing the magnetite in styrene where

bis(2-ethyl, hexyl) sulphosuccinate (AOT) was used as dispersant. The dispersion was then miniemulsified in water using cethyltrimethyl

ammonium bromide (CTAB) as second emulsifier forming a stable emulsion. The miniemulsion polymerization was carried out at 60 ◦C and

was initiated with 2,2-Azobisisobutyronitrile (AIBN). The latexes obtained were characterized by X-ray diffraction (XRD), magnetometry

and transmission electron microscopy.
