| titleOfInvention | Catalyst component for α-olefin polymerization |
| abstract | Abstract: PROBLEM TO BE SOLVED: To provide a novel transition metal compound which can be a catalyst component for α-olefin polymerization, which can obtain a high molecular weight and high melting point olefin polymer in a high yield. A novel transition metal compound represented by the following general formula (Ia). Embedded image (In the general formula (Ia), R 1 , R 2 , R 4 , and R 5 are each independently a hydrogen atom, a hydrocarbon group having 1 to 10 carbon atoms, or a silicon-containing hydrocarbon group having 1 to 18 carbon atoms. or a halogenated hydrocarbon group having 1 to 18 carbon atoms .R 3 and R And 6 each independently represents a saturated or unsaturated divalent hydrocarbon group having 3 to 10 carbon atoms which forms a condensed ring with the five-membered ring to which it is bonded. However, at least one of R 3 and R 6 has 5 to 8 carbon atoms and forms a condensed ring composed of a 7- to 10-membered ring having an unsaturated bond derived from R 3 or R 6 . R 7 and R 8 are each independently a hydrocarbon group having 1 to 20 carbon atoms, a halogenated hydrocarbon group having 1 to 20 carbon atoms, an oxygen-containing hydrocarbon group having 1 to 20 carbon atoms, an amino group, A nitrogen-containing hydrocarbon group having 1 to 20 carbon atoms or a sulfur-containing hydrocarbon group having 1 to 20 carbon atoms is shown. However, R 7 And at least one of R 8 is a halogenated hydrocarbon group having 1 to 20 carbon atoms. m and n are each independently 0 Represents an integer of up to 20. However, m and n do not become 0 at the same time. When m or n is 2 or more, R 7 and R8 may be linked to each other to form a new ring structure. Q is a divalent hydrocarbon group having 1 to 20 carbon atoms, a silylene group which may have a hydrocarbon group having 1 to 20 carbon atoms, an oligosilylene group, a germylene group, which bonds two five-membered rings. Is shown. X and Y each independently represent a hydrogen atom, a halogen atom, a carbon number of 1 to 20; Hydrocarbon group, a silicon-containing hydrocarbon group having 1 to 20 carbon atoms, a halogenated hydrocarbon group having 1 to 20 carbon atoms, and 1 carbon atom To 20 oxygen-containing hydrocarbon groups, amino groups or 1 carbon atoms -20 represents a nitrogen-containing hydrocarbon group, and M represents a periodic table 4-6. 1 shows a group transition metal. ) |
