BOROHYDRIDE METALLOCENE COMPLEX OF A LANTHANIDE, CATALYTIC SYSTEM INCLUDING SAID COMPLEX, POLYMERISATION METHOD USING SAME AND ETHYLENE/BUTADIENE COPOLYMER OBTAINED USING SAID METHOD
摘要:
The invention relates to a borohydride metallocene complex of a lanthanide, the preparation method thereof, a catalytic system including said borohydride metallocene complex and a method for the copolymerisation of olefins using said catalytic system. The inventive complex has one of the following formulas (A and B), wherein, in formula A, two ligands Cp 1 and Cp 2 are linked to the lanthanide Ln, such as Nd, said ligands each consisting of a cyclopentadienyl group, and, in formula B, a ligand molecule is linked to the lanthanide Ln, said ligand molecule consisting of two cyclopentadienyl groups Cp 1 and Cp 2 which are interlinked by means of a bridge P having formula MR 1 R 2 , in which M is an element from column IVA, such as Si, and R 1 and R 2 , which may be identical or different, represent an alkyl group having between 1 and 20 carbon atoms. According to the invention, L represents an alkali metal, such as Li, N represents a molecule of a complexing solvent, such as THF, x is an integer or a non-integer which is greater than 0, p is an integer which is equal to or greater than 1 and y is an integer which is equal to or greater than 0.
