Abstract

To provide an industrially useful α-olefin.((meth)acrylic acid)-based olefin copolymer having both a high molecular weight and a high comonomer content, a catalyst component capable of realizing a production of two different kinds of α-olefin.((meth)acrylic acid)-based olefin copolymers, and a production process using the catalyst. An α-olefin.((meth)acrylic acid)-based olefin copolymer is produced by using a metal complex complexed with a ligand represented by the following formula (Y is phosphorus or arsenic) for a catalyst composition.

First claim

The invention claimed is:

1. A metal complex represented by the following formula (2):

wherein Y is phosphorus or arsenic, Z is —SO 3 — or CO 2 —, wherein R 1 is a hydrogen atom, R 2 is a secondary alkyl group having from 3 to 6 carbon atoms, R 3 is a hydrogen atom, and R 4 is a secondary alkyl group having from 3 to 6 carbon atoms, each of R 5 to R 14 independently represents a hydrogen atom, a halogen atom, or a hydrocarbon group having a carbon number of 1 to 30, which may have a heteroatom, M represents a metal atom selected from the group consisting of transition metals of Groups 8 to 10 of the periodic table, A represents a hydrogen atom, an alkyl group having a carbon number of 1 to 30, which may have a heteroatom, or an aryl group having a carbon number of 6 to 30, which may have a heteroatom, B represents an arbitrary ligand coordinated to M, and A and B may combine with each other to form a ring.

2. An α-olefin polymerization catalyst comprising the metal complex claimed in claim 1 .

3. An α-olefin polymerization catalyst comprising the metal complex claimed in claim 1 and a fine particle support.

4. The α-olefin polymerization catalyst as claimed in claim 3 , wherein the fine particle support is an ion-exchanging layered silicate.

5. The α-olefin polymerization catalyst as claimed in claim 4 , wherein the ion-exchanging layered silicate belongs to a smectite group.

6. A process for producing an α-olefin.((meth)acrylic acid)-based copolymer, comprising copolymerizing an α-olefin and a (meth)acrylic acid or ester in the presence of the α-olefin polymerization catalyst claimed in any one of claims 2 or 3 .

7. A process for producing an α-olefin.(meth)acrylic acid)-based copolymer, comprising copolymerizing three components: two different α-olefins; and a (meth)acrylic acid or ester, in the presence of the α-olefin polymerization catalyst claimed in any one of claims 2 or 3 .
