Abstract

An anti-static agent containing a polyether compound having a cationic group is provided. According to the present invention, an anti-static agent can be provided which has excellent compatibility with a resin material and a rubber material as well as excellent anti-static properties.

First claim

The invention claimed is:

1. A composition for a formed product,
wherein the composition is a blend of an anti-static agent containing a polyether compound having a cationic group and a resin and/or rubber formed by blending the anti-static agent and the resin and/or rubber, wherein
a content of the polyether compound having a cationic group is 0.1 to 30 parts by weight based on a total of 100 parts by weight of the resin and the rubber.

2. A formed product obtained by forming the composition for a formed product according to claim 1 .

3. A cross-linkable composition
wherein the cross-linkable composition is a blend of an anti-static agent containing a polyether compound having a cationic group, a resin and/or rubber, and a cross-linking agent formed by blending the anti-static agent, the resin and/or rubber and the cross-linking agent, wherein
a content of the polyether compound having a cationic group is 0.1 to 30 parts by weight based on a total of 100 parts by weight of the resin and the rubber.

4. A cross-linked product obtained by cross-linking the cross-linkable composition according to claim 3 .

5. A laminate comprising a layer of a formed product of a resin and/or rubber and a layer of an anti-static agent formed by cross-linking a composition for an anti-static agent, the composition comprising a polyether compound having a cationic group and a cross-linking agent, wherein
a thickness of the layer of the formed product of the resin and/or rubber is 10 to 1,000 μm and a thickness of the layer of the anti-static agent is 0.01 to 100 μm.

6. The composition for a formed product according to claim 1 , wherein the polyether compound having a cationic group includes a monomer unit represented by the following general formula (1):

wherein A + represents a cationic group or cationic group-containing group, X − represents an arbitrary counter anion, R represents a non-ionic group, “n” is an integer of 2 or more, “m” is an integer of 0 or more, and “n+m” is an integer of 5 to 1000.

7. The composition for a formed product according to claim 1 , wherein the resin and/or rubber are at least one of selected from the group consisting of polyethylene terephthalate resin, acrylic resin, styrene butadiene rubber, and fluorine rubber.

8. The cross-linkable composition according to claim 3 , wherein the polyether compound having a cationic group includes a monomer unit represented by the following general formula (1):

wherein A + represents a cationic group or cationic group-containing group, X − represents an arbitrary counter anion, R represents a non-ionic group, “n” is an integer of 2 or more, “m” is an integer of 0 or more, and “n+m” is an integer of 5 to 1000.

9. The cross-linkable composition according to claim 3 , wherein the resin and/or rubber are at least one of selected from the group consisting of polyethylene terephthalate resin, acrylic resin, styrene butadiene rubber, and fluorine rubber.

10. The laminate according to claim 5 , wherein the polyether compound having a cationic group includes a monomer unit represented by the following general formula (1):

wherein A + represents a cationic group or cationic group-containing group, X − represents an arbitrary counter anion, R represents a non-ionic group, “n” is an integer of 2 or more, “m” is an integer of 0 or more, and “n +m” is an integer of 5 to 1000.

11. The laminate according to claim 5 , wherein the resin and/or rubber are at least one of selected from the group consisting of polyethylene terephthalate resin, acrylic resin, styrene butadiene rubber, and fluorine rubber.
