Catalyst support and catalyst for alpha-olefin polymerization; processes for preparing them and polymerization of alpha-olefins in the presence of the catalyst |
摘要 |
<p>Catalyst support containing an alpha -olefin polymer in the form of particles of mean size from 5 to 350 mu m in which the pore volume produced by the pores of radius from 1000 to 75,000 ANGSTROM is at least 0.2 cm<3>/g. Catalyst usable for the polymerisation of alpha -olefins, including a compound containing at least one transition metal belonging to groups IIIb, IVb, Vb and VIb of the Periodic Table, bound into or onto this support.</p> |
