Claim of US Patent No. 10,363,555

1. A dopant polymer for a conductive polymer, having(i) one or more repeating units “a” represented by the following general formula (1),

wherein R1 represents a hydrogen atom or a methyl group, R2 represents a fluorine atom or a trifluoromethyl group, “m” represents an integer of 2 to 4, and a number of “a” repeating units as a proportion of a total number of all repeating units in the dopant polymer satisfies 0 (ii) at least one repeating unit “b” represented by the following general formula (2),

wherein a number of “b” repeating units as a proportion of the total number of all repeating units in the dopant polymer satisfies 0 wherein the dopant polymer for the conductive polymer has a weight average molecular weight in the range of 1,000 to 500,000.
