Abstract
The catalysts are composed of an organometallic compound and a solid catalytic component which is the reaction product of a transition metal derivative and a solid support having a composition, at least on its surface, which corresponds to the formula M(OH).sub.x X.sub.y.nH.sub.2 O wherein X is a halogen, M is a bivalent metal 1>x>0, y=2-x, and 1>n.gtoreq.o. Polymerization and copolymerization of olefins are carried out advantageously using the new catalysts.
