titleOfInvention | Ethylene/butadiene copolymer |
abstract | The present invention relates to a borohydride metallocene complex of lanthanide, a process for its preparation, a catalyst system comprising said borohydride metallocene complex, a process for the copolymerization of olefins using said catalyst system and a process for the preparation of butadiene units Is an ethylene / butadiene copolymer having 1,2-cyclohexane chains or 1,2- and 1,4-cyclohexane chains. The complexes of the present invention correspond to one of formulas A and B. A Formula B In the above formulas A and B, In formula A, two ligand molecules Cp 1 and Cp 2 , each of which consists of a fluorenyl group, are bonded to lanthanide Ln, for example Nd, In formula (B), a bridge P of the formula MR 1 R 2 , wherein M is a Group IVa element such as Si, R 1 and R 2 are the same or different and are alkyl groups of 1 to 20 carbon atoms A ligand molecule composed of two fluorenyl groups Cp 1 and Cp 2 bonded to each other is bonded to lanthanide Ln, L is an alkali metal, for example Li, N is a molecule of a complexing solvent such as THF, x is an integer or non-integer greater than zero, p is an integer of 1 or more. |
