FIELD: catalyst carrier materials.
SUBSTANCE: microspherical particles are manufactured by adding specified proportion of fine, preferably reused particles to suspension of silica sol and silica powder, which suspension is then subjected to spray drying to form microspherical particles, which are finally calcined. Thus obtained particles are suitable for use as carrier for catalytically active component when preparing catalyst employed in fluidized-bed form in production of monomers used as vinyl polymer precursors.
EFFECT: increased abrasion resistance of particles.
