Abstract: Disclosed is an adhesive agent set composed of a main agent and a hardening agent, in which the main agent contains a urethane prepolymer having isocyanate groups as terminal groups; and an oligomer of hexamethylene diisocyanate having an isocyanate group modified with a silane coupling agent having a mercapto group or an amino group, the oligomer also having at least two unmodified isocyanate groups, and the hardening agent contains a polyol.

Abstract: A polymer includes: a structural unit represented by the following Formula (I-1) and a structural unit represented by the following Formula (I-2). In Formulae (I-1) and (I-2), X and X? each independently represent a divalent group having 6 to 50 carbon atoms and containing an aromatic ring; Y represents a divalent group having 5 to 50 carbon atoms, the divalent group including an alicyclic ring and alkylene groups, and the alkylene groups each having 1 to 10 carbon atoms connecting carbon atoms included in carbonyl groups adjacent to Y with the alicyclic ring; Y? represents a divalent group having 3 to 50 carbon atoms and containing an alicyclic ring directly bonded to carbon atoms included in carbonyl groups adjacent to Y?; and m and n each represent an integer from 3 to 1,000.
