| titleOfInvention | Ionic liquids as solvents in metallocene catalysis |
| abstract | The present invention discloses a method for preparing a dissolved catalystncomponent comprising the steps of:n a) providing a halogenated precursor component of formula (I)n ---X-[-CH 2 -]-CH 3 b) reacting the halogenated precursor with an ionic liquid precursor in ansolvent to prepare an ionic liquid;n IL + X - c) optionally, reacting the intermediate IL + X - with a salt C + A - , wherein C + is ancation that can be selected from K + , Na + , NH 4 + , and A - is an anion that cannbe selected from PF 6 - , SbF 6 - , BF 4 - , (CF 3 -SO 2 ) 2 N - , ClO 4 - , CF 3 SO 3 - , NO 3 - ornCF 3 CO 2 - . d) using the ionic liquid prepared in step b) to dissolve a metallocenencomponent of formula (II)n R" (CpR m ) (Cp'R n ) M Q 2 nwherein Cp and C'p are independently selected from substituted ornunsubstituted cyclopentadienyl groups M is a metal selected from Group 4 ofnthe Periodic Table, R" is a structural bridge imparting stereorigidity betweennCp and Cp' and Q is a halogen or an alkyl having from 1 to 12 carbonnatoms; e) retrieving a metallocene catalyst component dissolved in an ionic liquid. n It also discloses an active catalyst system dissolved in an ionic liquid and its usenin the polymerisation of olefins. |
