| titleOfInvention | Dinuclear metallocene catalyst and preparation method and application thereof |
| abstract | The invention relates to a dinuclear metallocene catalyst and a preparation method and application thereof, wherein the catalyst comprises a main catalyst and an auxiliary catalyst, wherein the main catalyst is formed by two molecules of an organic metal complex which contains IVB-IIB group transition metal atoms and is coordinated with cyclopentadienyl or substituted cyclopentadienyl through rigid group bridging. The catalyst is matched with an activating cocatalyst to be used for ethylene/alpha-olefin solution copolymerization reaction, shows excellent polymerization activity and copolymerization performance, and can be used for preparing ethylene/alpha-olefin random copolymer with high molecular weight and high alpha-olefin content. |
