Abstract

A compound represented by the following general formula (1):

First claim

The invention claimed is:

1. A compound represented by the following formula (1):

in which X represents a nitrogen atom, Y represents a phosphorus atom,
R 5 and R 6 each independently is a hydrogen atom or a hydrocarbon group which has 1-30 carbon atoms and may contain one or more heteroatoms, at least one of R 5 and R 6 being a hydrocarbon group which contains two or more heteroatom-containing groups, and
R 1 to R 4 each independently represents a hydrogen atom, a hydrocarbon group which has 1-20 carbon atoms and may contain one or more heteroatoms, or a halogen atom, and two or more groups selected from among R 1 to R 4 may be linked to each other to form an alicyclic ring, an aromatic ring, or a heterocyclic ring which contains one or more heteroatoms selected from among oxygen, nitrogen, and sulfur atoms, in which each of the rings is a 5- to 8-membered ring which may have one or more substituents thereon.

2. The compound according to claim 1 , wherein R 3 and R 4 are linked to each other to form an aromatic ring.

3. A metal complex obtained by reacting a compound according to formula (1) with a complex precursor which is a compound of a transition metal belonging to Groups 8 to 10 of the periodic table, wherein the compound of formula (1) is

in which X represents a nitrogen atom, Y represents a phosphorus atom,
R 5 and R 6 each independently is a hydrogen atom or a hydrocarbon group which has 1-30 carbon atoms and may contain one or more heteroatoms, at least one of R 5 and R 6 being a hydrocarbon group which contains two or more heteroatom-containing groups, and
R 1 to R 4 each independently represents a hydrogen atom, a hydrocarbon group which has 1-20 carbon atoms and may contain one or more heteroatoms, or a halogen atom, and two or more groups selected from among R 1 to R 4 may be linked to each other to form an alicyclic ring, an aromatic ring, or a heterocyclic ring which contains one or more heteroatoms selected from among oxygen, nitrogen, and sulfur atoms, in which each of the rings is a 5- to 8-membered ring which may have one or more substituents thereon.

4. The metal complex according to claim 3 , which is represented by the following formula (2)

in which M represents a transition metal belonging to Groups 8 to 10 of the periodic table,
X represents a nitrogen atom, Y represents a phosphorus atom,

R 1 to R 4 , R 7 , and R 8 each independently represents a hydrogen atom, a hydrocarbon group which has 1-20 carbon atoms and may contain one or more heteroatoms, or a halogen atom, and two or more groups selected from among R 1 to R 4 , R 7 , and R 8 may be linked to each other to form an alicyclic ring, an aromatic ring, or a heterocyclic ring which contains one or more heteroatoms selected from among oxygen, nitrogen, and sulfur atoms, in which each of the rings is a 5- to 8-membered ring which may have one or more substituents thereon.

5. The metal complex according to claim 4 , wherein M in formula (2) is a transition metal belonging to Group 10 of the periodic table.

6. A catalyst component for olefin polymerization which comprises the metal complex according to claim 3 .

7. A catalyst for olefin polymerization which comprises the following components (A) and (B), and optionally further contains the following component (C):
component (A): the metal complex according to claim 3 ,
component (B): either a compound which reacts with component (A) to form an ion pair, or an ion-exchange phyllosilicate,
component (C): an organoaluminum compound.

8. The catalyst for olefin polymerization according to claim 7 , wherein the component (B) is an aluminoxane.

9. A process for producing an α-olefin polymer, the process comprising polymerizing or copolymerizing (a) α-olefin in the presence of the catalyst for polymerization according to claim 7 .

10. A process for producing an α-olefin/polar comonomer copolymer, the process comprising copolymerizing (a) α-olefin with (b) a polar comonomer in the presence of the catalyst for polymerization according to claim 7 .
