Abstract

The present disclosure provides a novel transition metal compound having excellent structural stability together with polymerization reactivity, and thereby is useful as a catalyst in preparing an olefin-based polymer, particularly, a low density olefin-based polymer, and a catalyst composition including the same.

First claim

What is claimed is:

1. A ligand compound of the following Chemical Formula 2:

wherein, in Chemical Formula 2,
R is selected from the group consisting of a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an arylalkyl group having 7 to 20 carbon atoms, and an alkylaryl group having 7 to 20 carbon atoms; or R and R 1 are linked to each other to form an aliphatic ring having 3 to 20 carbon atoms or an aromatic ring having 5 to 20 carbon atoms including N;
R 1 to R 10 are each independently selected from the group consisting of a hydrogen atom, a halogen group, an alkyl group having 1 to 20 carbon atoms, an alkenyl group having 2 to 20 carbon atoms, a cycloalkyl group having 3 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an arylalkyl group having 7 to 20 carbon atoms, an alkylaryl group having 7 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, an aryloxy group having 6 to 20 carbon atoms, and a silyl group, or two or more adjacent functional groups among R 1 to R 10 are linked to each other to form an aliphatic ring having 3 to 20 carbon atoms or an aromatic ring having 6 to 20 carbon atoms;
R 11 is selected from the group consisting of a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, an alkenyl group having 2 to 20 carbon atoms, a cycloalkyl group having 3 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an arylalkyl group having 7 to 20 carbon atoms, an alkylaryl group having 7 to 20 carbon atoms, a silyl group, and a metalloid radical of a group 14 metal substituted with a hydrocarbyl group having 1 to 20 carbon atoms;
R, and R 1 to R 11 are each independently unsubstituted or substituted with one or more substituents selected from the group consisting of a halogen group, an alkyl group having 1 to 20 carbon atoms, a haloalkyl group having 1 to 20 carbon atoms, an alkenyl group having 2 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an arylalkyl group having 7 to 20 carbon atoms, an alkylaryl group having 7 to 20 carbon atoms and an aryloxy group having 6 to 20 carbon atoms; and
n is an integer of 1 or 2, and when n is an integer of 2, R 11 s are the same as or different from each other.

2. The ligand compound of claim 1 , which is selected from the group consisting of compounds of the following Chemical Formulae 2-1 to 2-12:
