Solid catalyst for polymerizing an olefin |
摘要 |
<p>A solid catalyst for polymerizing an olefin is prepared from an organometallic compound, a fine-particle carrier, an aluminoxane, a compound of group IVB transition metal in periodic table, and an olefin polymer produced in a preliminary polymerization. The catalyst has a high polymerization activity and is capable of producing an olefin polymer having a narrow molecular-weight distribution. When the catalyst is used for producing an olefin copolymer, the resulting copolymer has both narrow molecular-weight distribution and composition distribution.</p> |
