Catalyst support and catalyst for the polymerization of alpha-olefins; processes for obtaining them and polymerization of alpha-olefins in presence of the catalyst |
摘要 |
Catalyst support containing an alpha -olefin polymer which is in the form of particles of mean size from 5 to 350 mu m in which the pore volume generated by the pores of radius from 1,000 to 75,000 ANGSTROM is at least 0.2 cm3/g. Catalyst usable for the polymerization of alpha -olefins, including a compound containing at least one transition metal belonging to groups IIIb, IVb, IVb and VIb of the Periodic Table, bound in or on this support.
