Abstract
Adsorbent alumina particulates which comprise coagulated droplets, extrudates or crushed alumina particles having a volume of pores with a diameter greater than 80 .ANG. of at least 0.15 cm.sup.3 /g and a particle size of less than 4 mm are well suited for adsorbing chelated organometallic compound values thereon, in particular from a medium of polymerization comprising same.
