ELECTRICALLY CONDUCTING POLYMER, METHOD FOR PREPARING THE SAME AND ELECTROLYTIC CAPACITOR COMPRISING THE SAME

摘要

An electrically conducting polymer composition which comprises an electron conjugated polymer and at least one stationary dopant which is selected from the group consisting of consisting of an oligomer having ionic groups with an average degree of oligomerization of 3 to 12 and ionic group-bonded particles which have an average particle size of 0.01 to 1 mu m and to at least surfaces of which ionic groups are bonded through covalent bonds, and which is dispersed in said electron conjugated polymer, which polymer composition provides an electrolytic capacitor having good frequency characteristics and long-term stability.
