▎ 摘　　要

NOVELTY - A polyether polymer composition comprises a polyether polymer containing two or more oxirane monomeric units and a cationic group in the portion(s) of a polymer chain terminal and/or the oxirane monomeric unit, and graphene. USE - Polyether polymer composition. Uses include but are not limited to electroconductive material for electrical/electronic products, thermal radiation material, building material, and medical material. ADVANTAGE - The polyether polymer composition has excellent dispersibility of graphene and electroconductivity.
