Process for preparing a hybrid catalyst for olefin polymerization, hybrid catalyst for olefin polymerization, and polyolefin

A process for preparing a supported hybrid metallocene catalyst for olefin polymerization, which comprises (1) mixing a first transition metal compound represented by Formula 1 with a first cocatalyst compound;

• (2) supporting the mixture of the first transition metal compound and the first cocatalyst compound obtained in step (1) on a carrier;
• and (3) mixing the supported catalyst obtained in step (2) with (3a) a mixture of a second transition metal compound represented by Formula 2 and a second cocatalyst compound, or (3b) a second transition metal compound represented by Formula 2, which is then mixed with a second cocatalyst compound, or (3c) a second cocatalyst compound, which is then mixed with a second transition metal compound represented by Formula 2:
• in Formulae 1 and 2, M is each independently 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, C6-20 arylamido, or C1-20 alkylidene,

• Q is an anionic leaving group and is each independently hydrogen, hydrocarbyl, heteroatom or halogen, a straight or branched chain alkyl radical, or an alkenyl radical, an alkynyl radical, a cycloalkyl radical or an aryl radical, an acyl radical, an aroyl radical, an alkoxy radical, an aryloxy radical, an alkylthio radical, a dialkylamino radical, an alkoxycarbonyl radical, an aryloxycarbonyl radical, a carbomoyl radical, an alkyl- or dialkyl-carbamoyl radical, an acyloxy radical, an acylamino radical, an aroylamino radical, a straight-chain, branched-chain or cyclic alkylene radical, or a combination thereof,
• n is the oxidation state of M and is +3, +4, or +5,
• o is the formal charge of the YZL ligand and is 0, −1, −2, or −3,
