Zusammenfassung:To provide a polymer that can maintain adhesive strength equal to or higher than that in the air even in wet conditions, and an adhesive including the same.SOLUTION: A polymer includes three or more side chains in a main chain, composed of poly(meth)acrylate. The first side chain A has a hydrophilic functional group, the second side chain B has an aromatic ring with two or more hydroxy groups at its terminal, and the third side chain C has a hydrophobic functional group.SELECTED DRAWING: None 【課題】本発明の目的は、湿潤環境下でも大気中と同等以上の粘接着力を維持できるポリマーおよびそれを含有する粘着剤を提供することにある。【解決手段】ポリ(メタ)アクリレートからなる主鎖に3種類以上の側鎖を有し、第1の側鎖Aは親水性の官能基を有し、第2の側鎖Bは末端にヒドロキシ基を2個以上含む芳香環を有し、第3の側鎖Cは疎水性の官能基を有する、ポリマー。【選択図】なし
