The invention relates to a catalyst composition comprising a salt of a non- or weakly coordinating anion, said non- or weakly coordinating anion comprising at least one metal or metalloid ion M with valency v+, v representing an integer between 1 and 5, and at least one bidentate ligand coordinating to this metal or metalloid ion, and a catalyst that can be activated by said non- or weakly coordinating anion, characterized in that said bidentate ligand is a bidentate monoanionic ligand of formula (I): (R

are each independently chosen from the group comprising an optionally substituted linear or branched (hetero)alkyl group, an optionally substituted (hetero)aryl group, and a Si containing group; and q and r each independently represent an integer with 0≦q, r≦2.
该发明涉及一种催化剂组合物,包括一种非或弱配位阴离子的盐,所述非或弱配位阴离子包括至少一个带有价态v+的金属或金属loid离子M,其中v代表介于1和5之间的整数,并且至少一个双齿配体与该金属或金属loid离子配位,以及一种可以由所述非或弱配位阴离子激活的催化剂,其特征在于所述双齿配体是具有以下式(I)的双齿单阴离子配体:(R1qA1-X-A2R2r),其中X代表桥接基;A1和A2分别独立地选择自N、O、P、S和C组成的群;R1和R2分别独立地选择自可选择的直链或支链(杂)烷基基团、可选择的(杂)芳基团和含Si基团;q和r各自独立地表示满足0≦q,r≦2的整数。
