ABSTRACT:
Magnetizable "core-shell" microspheres comprising a core of a magnetizable filler and a shell of crosslinked organopolysiloxane obtained by dispersing an aqueous suspension of a magnetizable filler, not coated with a dispersing agent, in an organic solvent, dissolving an organopolysiloxane and an organohydrogenpolysiloxane in the organic phase, crosslinking, removing water, separating and, if appropriate, redispersing the magnetizable microspheres in water.
