ABSTRACT:
A solid catalyst component for the polymerization and copolymerization of ethylene and alpha- olefins, containing a metallocene supported on an inorganic solid carrier constituted by a porous silicon oxide, the supported metallocene having the formula (I): ##STR1## wherein M is a group of metal, R' and R" are dialkylamide groups, R'" has the same definition as R' or is a cyclopentadienyl consisting ligand, and A is an anion containing an .eta..sup.5 -cyclopentadienyl ring coordinated to metal M, and wherein a carbon atom of the .eta..sup.5 -cyclopentadienyl ring of anion A is covalently bonded to the surface of the porous inorganic solid carrier.
