Abstract:
1. A fluoropolymer (A) having units derived from monomer units formed by cyclopolymerization of (I) at least one fluorinated diene selected from the group consisting of a fluorinated diene represented by the formula (1) and a fluorinated diene represented by the formula (2), and (II) units derived from monomer units formed by cyclopolymerization of a fluorinated diene represented by the formula (3): wherein R 1 represents a hydrogen atom, a blocked group of a hydroxyl group capable of being converted into a hydrogen atom by an acid, or a blocked carboxyl group-containing organic group capable of being converted into a carboxyl group-containing organic group by an acid, R 2 represents a hydrocarbon group having at most 20 carbon atoms, and n represents 0 or 1.
