Abstract
The present disclosure provides a supported hybrid catalyst which facilitates the preparation of polyolefins having improved bubble stability and exhibiting excellent processability for a blown film while maintaining high transparent haze and improved melt strength, and a method for preparing the same.
Claims11
A supported hybrid catalyst, comprising at least one first transition metal compound selected from compounds represented by the following Chemical Formula 1;
- at least one second transition metal compound selected from compounds represented by the following Chemical Formula 2;
- and
- a support on which the first and second transition metal compounds are supported,
- wherein, in Chemical Formula 1,
- M1 is a Group 4 transition metal;
- X1 and X2 are the same as or different from each other, and are each independently any one of a halogen, a nitro group, an amido group, a phosphine group, a phosphide group, a C1 to C30 hydrocarbyl group, a C1 to C30 hydrocarbyloxy group, a C2 to C30 hydrocarbyloxyhydrocarbyl group, —SiH3, a C1 to C30 hydrocarbyl(oxy)silyl group, a C1 to C30 sulfonate group, and a C1 to C30 sulfone group;
- R1 and R3 to R10 are the same as or different from each other, and are each independently selected from the group consisting of hydrogen, a C1 to C30 hydrocarbyl group, a C1 to C30 hydrocarbyloxy group, and a C2 to C30 hydrocarbyloxyhydrocarbyl group;
- R2 is selected from the group consisting of a C1 to C30 hydrocarbyl group, a C1 to C30 hydrocarbyloxy group, and a C2 to C30 hydrocarbyloxyhydrocarbyl group;

- and
- Ra and Rb are the same as or different from each other, and are each independently any one of hydrogen and a C1 to C30 hydrocarbyl group, or may be connected with each other to form an aliphatic or aromatic ring,
- wherein, in Chemical Formula 2,
- M2 is a Group 4 transition metal;
- X3 and X4 are the same as or different from each other, and are each independently any one of a halogen, a nitro group, an amido group, a phosphine group, a phosphide group, a C1 to C30 hydrocarbyl group, a C1 to C30 hydrocarbyloxy group, a C2 to C30 hydrocarbyloxyhydrocarbyl group, —SiH3, a C1 to C30 hydrocarbyl(oxy)silyl group, a C1 to C30 sulfonate group, and a C1 to C30 sulfone group;
- R11 to R24 are the same as or different from each other, and are each independently selected from the group consisting of hydrogen, a C1 to C30 hydrocarbyl group, a C1 to C30 hydrocarbyloxy group, and a C2 to C30 hydrocarbyloxyhydrocarbyl group;
- Q3 and Q4 are the same as or different from each other, and are each independently any one of hydrogen, a C1 to C30 hydrocarbyl group, a C1 to C30 hydrocarbyloxy group, a C2 to C30 hydrocarbyloxyhydrocarbyl group, —SiH3, a C1 to C30 hydrocarbyl(oxy)silyl group, a C1 to C30 hydrocarbyl group substituted with a halogen, and —NRa′Rb′;
- and
- Ra′ and Rb′ are the same as or different from each other, and are each independently any one of hydrogen and a C1 to C30 hydrocarbyl group, or may be connected with each other to form an aliphatic or aromatic ring.
