| titleOfInvention | Carbon and / or silicon bridged bimetallic metallocene catalyst for styrene polymerization, and styrene polymerization method using the same |
| abstract | The present invention relates to alkyl, silyl, or alkyl-silyl bridge bimetallic metallocene catalysts used in styrene polymerization or copolymerization and processes for their preparation.n n n The bimetallic metallocene catalyst is a π-electron cyclopentadienyl group capable of η 5 bonding; Cyclopentadienyl groups substituted with alkyl, alkoxy, silyl or halogen; Indenyl group; Indenyl groups substituted with alkyl, alkoxy, silyl or halogen; Fluorenyl group; Fluorenyl groups substituted with alkyl, alkoxy, silyl or halogen are prepared in salt form and reacted with alkyl compounds, silyl compounds or alkyl-silyl compounds to form cyclopentadienyl groups, indenyl groups, fluorenyl groups, or alkyl, alkoxy To generate an alkyl bridge, a silyl bridge, or an alkyl-silyl bridge compound, wherein two or more cycloalkanedienyl groups, which are selected from a silyl or halogen-substituted cyclopentadienyl group, an indenyl group, or a fluorenyl group are linked to each other, Alkyl, silyl or alkyl-silyl bridging compounds in the salt state are prepared by reacting an alkali metal having an alkyl or alkoxy group, followed by reacting the transition metal compound of Group IVb of the periodic table with the bridging compound in the salt state, or the salt Transition metal compound of group IVb of the periodic table after introducing a compound that falls well in the acid into the bridge compound of the state Prepared by reaction. |
