Ionic liquids as solvents |
摘要 |
The present invention discloses a method for preparing a dissolved catalyst component comprising the steps of: a) providing a halogenated precursor component of formula (I) X-[CH2-]- b) reacting the halogenated bisimine precursor with an ionic liquid precursor in a solvent to prepare an ionic liquid; c) mixing in a solvent one equivalent of the ionic liquid prepared in step b) with a metallic complex of formula (II) L<SUB>2</SUB>MY<SUB>2 </SUB>wherein L is a coordinating ligand for the metallic site, said coordination being achieved by phosphorus, nitrogen or oxygen; d) evaporating the solvent; and e) retrieving a hybrid single site catalyst component/ionic liquid system. It also discloses an active catalyst system heterogenised by an ionic liquid and its use in the polymerisation of olefins.
