Catalyst component for the polymerisation of olefins obtained by impregnation of a prepolymer with a solution of a catalytic component, and polymer obtained using said catalyst component. |
摘要 |
Process for preparing a catalyst compsn. for polymerisation of olefins comprises (a) forming a prepolymer by prepolymerisation in the presence of a solid catalytic compsn. (A), then impregnating the prepolymer with a soln. of a catalytic compsn. (B), with the proviso that the cpds. (A) and (B) are not such that simultaneously (i) the compsn. (A) comprises a cpd. having a cyclopentadienyl structure and a cpd. contg. an Al-O bond and (ii) the compsn. B contains two ligands each comprising a cyclopentadienyl structure bonded together by a bivalent radical.
