Abstract

An object of the present invention is to provide a macromolecular material that exhibits excellent elongation. The first macromolecular material of the present invention contains the first polymer containing the first structural unit and the second polymer containing the second structural unit. The first structural unit has a guest group in its side chain, and the second structural unit has a host group in its side chain. At least one of the first and the second polymers contains at least one fluorine group. The second macromolecular material of the present invention contains the first structural unit having a guest group in its side chain, the second structural unit having a host group in its side chain, and the third structural unit other than the first and second structural units. At least one of the first, the second, and the third structural units contains at least one fluorine group.
