Abstract

The invention relates to particles comprises of organopolysiloxane microgel particles having a diameter of 5 to 200 nm and organo-aluminum compounds immobilized thereon. The particles can be used as cocatalysts together with metal compounds of the 4, 5, 6 and 8-10 sub-groups of the periodic table for oligomerization, cyclization of polymerization of olefins.
