Abstract: The present invention relates to a new bimetallic complex of the formula (1) wherein: M is a group 4-6 metal R1 means is a substituent comprising a heteroatom of group 15, through which R1 is bonded to the imine carbon atom; R2-R6 are the same or different and each represents a hydrogen atom, an optionally substituted C1-10 alkyl group, an optionally substituted C1-10 alkoxy group, an optionally substituted C6-20 aryl group, an optionally substituted C6-20 aryloxy group, an optionally substituted C7-20 aralkyl group, an optionally substituted C7-20 aralkyloxy group, a silyl group substituted with optionally substituted C1-20 hydrocarbon group(s), a C1-20 hydrocarbon-substituted amino group or the adjacent R2-R6 may be linked to each other to form a ring; R7-R10 are the same or different and each represents a hydrogen atom, a halogen atom, an optionally substituted C1-10 alkyl group, an optionally substituted C1-10 alkoxy group, an optionally substituted C6-20 aryl group, an optionally substituted C6-20 arylox

Abstract: A catalyst system comprising a) a metal complex of the formula CyLMZp, wherein M is a group 4 metal Z is an anionic ligand, p is number of 1 to 2, preferably 2 Cy is a cyclopentadienyl-type ligand and, L is a ligand of the formula wherein each A is independently selected from the group consisting of nitrogen and phosphorus and R1, R2, and R4 are independently selected from the group consisting of hydrogen, unsubstituted or substituted hydrocarbyl, unsubstituted or substituted silyl and unsubstituted or substituted germyl residues, and b) a boron containing activator, characterized in that the molar ratio of the boron of the activator to M of the metal complex is greater than 2.5.
