Abstract
Process for the preparation of magnetic beads of vinylaromatic polymers, which comprises dispersing a magnetic filler in a solution of a homo- or co-polymer in a vinylaromatic compound alone or in mixture with a co-polymerizable monomer, putting the resulting dispersion into suspension in water and polymerizing the monomer or monomers, and use of said magnetic beads in the paints, inks, reprography and in biology.
