Fluoropolymer, aqueous solution, coating composition and method for producing fluoropolymer

Abstract

Provided is a fluoropolymer containing a polymerization unit (I) derived from a monomer (I) represented by the general formula (I) and a polymerization unit (II) derived from a monomer (II) represented by the formula (II): CX1X3═CX2R(—CZ1Z2-A0)m  (I) wherein X1 and X3 are each independently F, Cl, H, or CF3; X2 is H, F, an alkyl group, or a fluorine-containing alkyl group; A0 is an anionic group; R is a linking group; Z1 and Z2 are each independently H, F, an alkyl group, or a fluorine-containing alkyl group; and m is an integer of 1 or more; and CHF═CHF  (II)

Dependencies are inferred from the claim text.
