Abstract

The present invention is a polyether-based polymer composition includes: a polyether-based polymer including an oxirane monomer unit and having one cationic group substantially only at one terminal of a polymer chain, and a nanocarbon material. The polyether-based polymer composition of the present invention can be suitably used, for example, as a bucky gel or as a master batch for preparing a nanocarbon material aqueous dispersion in which a nanocarbon material is favorably dispersed.

First claim

The invention claimed is:

a nanocarbon material,

wherein in the formula (1), R represents a nonionic group,

wherein in the formula (2), R represents a nonionic group, A + represents a cationic group, X − represents a counter anion, and n represents an integer of 20 or more.

2. The polyether-based polymer composition according to claim 1 , wherein R represents a methyl group in the formula (2).

3. The polyether-based polymer composition according to claim 1 , wherein the nanocarbon material is a carbon nanotube.

4. The polyether-based polymer composition according to claim 1 , wherein a content of the nanocarbon material is 0.01 to 30 parts by weight based on 100 parts by weight of the polyether-based polymer.

5. The polyether-based polymer composition according to claim 1 , wherein water is further contained and a content of the nanocarbon material is 0.05 wt % or more based on the whole composition.

6. The polyether-based polymer composition according to claim 1 , wherein the content of the oxirane monomer unit in the polyether-based polymer being 95 wt % or more in the whole monomer units.
