Mixed catalytic composition, catalyst comprising the same, and processes for preparing the same

A process for preparing a hybrid catalytic composition, which comprises (1) dissolving a compound represented by Formula 4 and a compound represented by Formula 5 in a solvent;

• and (2) adding a compound represented by Formula 6 to a solution obtained in step (1) and reacting it under stirring to obtain a hybrid catalytic composition comprising at least two kinds of the transition metal compounds represented by Formulae 1 to 3, wherein a molar ratio of the compound represented by Formula 4 to the compound represented by Formula 5 is in the range of 10:1 to 1:10,
• wherein the compound represented by Formula 4 is at least one of the compounds represented by Formulae 4-1 to 4-12, and the compound represented by Formula 5 is at least one of the compounds represented by Formulae 5-1 to 5-6:
• in Formulae 1 to 6,
• M is each titanium (Ti), zirconium (Zr), or hafnium (Hf),
• X is each independently halogen, C1-20 alkyl, C2-20 alkenyl, C2-20 alkynyl, C6-20 aryl, C1-20 alkyl C6-20 aryl, C6-20 aryl C1-20 alkyl, C1-20 alkylamido, or C6-20 arylamido,
• R1 to R5 and R6 to R10 are each independently hydrogen, substituted or unsubstituted C1-20 alkyl, substituted or unsubstituted C2-20 alkenyl, substituted or unsubstituted C6-20 aryl, substituted or unsubstituted C1-20 alkyl C6-20 aryl, substituted or unsubstituted C6-20 aryl C1-20 alkyl, substituted or unsubstituted C1-20 heteroalkyl, substituted or unsubstituted C3-20 heteroaryl, substituted or unsubstituted C1-20 alkylamido, substituted or unsubstituted C6-20 arylamido, or substituted or unsubstituted C1-20 silyl, and
• R1 to R5 and R6 to R10 each independently may be linked to adjacent groups to form a substituted or unsubstituted, saturated or unsaturated C4-20 ring,
