  • Patent number: 10303051
    Abstract: Provided is a hyperbranched polymer having such a backbone that is readily decomposable by an acid. The hyperbranched polymer is derived from, via reaction, monomers including a monomer (X) and a monomer (Y). The monomer (X) contains three or more hydroxy groups per molecule. The monomer (Y) contains two or more groups represented by General Formula (y) per molecule. The monomer (X) includes at least one compound selected from the group consisting of cyclodextrins, compounds represented by General Formula (I), pillararenes, compounds represented by General Formula (II), compounds represented by General Formula (III), and compounds represented by General Formula (IV). The monomer (Y) includes a compound represented by General Formula (1).
