Abstract:
1. A polymer comprising recurring units of a fluorinated carboxylic acid onium salt having the general formula (1): wherein R 1 is a structure derived from a basis skeleton capable of providing the polymerization activity of a polymerizable monomer, represented by any one of the formulae: wherein the valence bond extending from the oxygen atom in the structure designates a bond to W 1 , R W Q wherein R 3 , R 4 and R 5 are each independently a substituted or unsubstituted, straight or branched C 1 -C 10 alkyl, alkenyl or oxoalkyl group or a substituted or unsubstituted C 6 -C 18 aryl, aralkyl or aryloxoalkyl group, or at least two of R 3 , R 4 and R 5 may bond together to form a ring with the sulfur atom, wherein R 6 is a substituted or unsubstituted, straight, branched or cyclic C 1 -C 20 alkyl or alkenyl group or a substituted or unsubstituted C 6 -C 14 aryl group, m is an integer of 1 to 5, n is 0 or 1, R 6 may have a carbonyl group, hydroxyl group, ester structure, lactone structure, amino group, amide group or ether-bonding oxygen atom substituted thereon
