Abstract: To provide a fluorinated elastic copolymer excellent in adhesion, processability, mechanical properties, heat resistance and chemical resistance.
A fluorinated elastic copolymer having units based on a monomer (a), units based on a monomer (b) and optionally units based on a monomer (c), which has an iodine atom bonded to a terminal of a molecular chain and the unit based on the monomer (b) adjacent to the iodine atom, and which has a proportion of the units based on the monomer (b) of from 0.09 to 2.0 mol % to all units. Monomer (a): monomer selected from the group consisting of tetrafluoroethylene, hexafluoropropylene, vinylidene fluoride, chlorotrifluoroethylene, a perfluoro(alkyl vinyl ether) and 2,3,3,3-tetrafluoropropene; monomer (b): a monomer having at least one type of functional group selected from the group consisting of an epoxy group, a hydroxy group, a carbonyl group-containing group and an isocyanate group; monomer (c): a monomer selected from the group consisting of ethylene and propylene.
