Abstract
A process for producing a carboxyl group-containing fluoropolymer comprises reacting a hydroxyl group-containing fluoropolymer in an organic solvent with a dibasic acid anhydride represented by the general formula ##STR1## where R represents a bifunctional organic group, to convert at least a part of hydroxyl groups into ester groups represented by the general formula ##STR2## where R is as defined above.
