Abstract:
A preparation method for a metallocene compound is provided. The method includes: stirring at least one compound I among compounds expressed by the following chemical formula (I) and a hydrogenation reaction catalyst of 0.10 to 0.55 parts by weight based on 100 parts by weight of the compound I under a hydrogen atmosphere; and obtaining a metallocene compound containing at least one first compound among the compounds expressed by the following chemical formula (1). Chemical formula (I) and (1) are provided in the specification.

Claim (Index 7):
The method of  claim 1 , wherein the metallocene compound further comprises at least one second compound among the compounds expressed by the following chemical formula (2): in the chemical formula (2), M is any one of titanium (Ti), zirconium (Zr) or hafnium (Hf); Q is any one of carbon (C), silicon (Si), germanium (Ge), or tin (Sn); X is independently any one of halogen, an alkyl group having 1 to 10 carbon atoms, and an alkenyl group having 2 to 10 carbon atoms; R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , and R 12  satisfy the following (i) or (ii), and each of R 13  and R 14  is independently an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 14 carbon atoms. (i) each of R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , and R 12  is independently any one of hydrogen, an alkyl group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms and an aryl group having 6 to 14 carbon atoms. (ii) among R m  (m is an integer of 1 to 12), two adjacent R n  and R n+1  (n is an integer from 1 to 11) are connected to each other to form a monocyclic or polycyclic rings having 3 to 15 carbon atoms in which the alkyl group having 1 to 4 carbon atoms is substituted or not substituted, and at this time, the remaining R m  except R n  and R n+1  is independently any one of hydrogen, an alkyl group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms and an aryl group having 6 to 14 carbon atoms.
