Abstract
Official abstract text for this publication.
A polyether polymer composition containing 50 parts by weight or more of a filler per 100 parts by weight of a polyether polymer composed of 10 to 200 oxirane monomer units is provided. The present invention can provide a polyether polymer composition that is capable of appropriately showing various properties of the filler such as high heat conductivity and high electrical conductivity and that also has excellent long-term stability.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polyether polymer composition comprising 50 parts by weight or more of a filler per 100 parts by weight of a polyether polymer composed of 10 to 200 oxirane monomer units. 2. The polyether polymer composition according to claim 1 , wherein the filler is a metal-containing powder. 3. The polyether polymer composition according to claim 2 , wherein the metal-containing powder is at least one selected from a metal powder, a metal oxide powder, and a metal nitride powder. 4. The polyether polymer composition according to claim 1 , wherein at least a part of the oxirane monomer unit composing the polyether polymer is an oxirane monomer unit having a cationic group. 5. The polyether polymer composition according to claim 4 , wherein the polyether polymer comprises a monomer unit represented by the following general formula (1): wherein A + represents a cationic group or a cationic group-containing group, X − represents any counter anion, R represents a non-ionic group, n is an integer of 1 or more, m is an integer of 0 or more, and n+m satisfies 10≤n+m≤200. 6. The polyether polymer composition according to claim 4 , wherein the cationic group comprises a heterocyclic ring having a cationic nitrogen atom. 7. The polyether polymer composition according to claim 1 , wherein an average particle size of the filler is 0.01 μm or more and less than 50 μm. 8. The polyether polymer composition according to claim 1 being a heat dissipating polymer composition. 9. The polyether polymer composition according to claim 1 being an electrically conductive polymer composition. 10. The polyether polymer composition according to claim 1 being in a grease form or a paste form.
