Abstract: Provided are a composition for polymerization from which a macromolecular material that contains a host-group-introduced polymer with excellent energy to failure can be produced without using a solvent; a polymer of the composition; and a method for producing the polymer. The composition for polymerization contains a solution containing a first polymerizable compound and a host-group-containing polymerizable compound that is dissolved in the first polymerizable compound, wherein the host group present in the host-group-containing polymerizable compound is a group formed by removing one hydrogen atom or hydroxy group from a cyclodextrin, and wherein the cyclodextrin is at least one cyclodextrin selected from the group consisting of α-cyclodextrin, β-cyclodextrin, and γ-cyclodextrin.

Abstract: Provided are a host-group-containing polymerizable monomer usable as a starting material for producing a macromolecular material with a high degree of freedom in material design, and excellent toughness and strength; a macromolecular material produced using the host-group-containing polymerizable monomer; and a method for producing the macromolecular material. The host-group-containing polymerizable monomer according to the present invention is a host-group-containing polymerizable monomer, and the host group is a monovalent group formed by removing one hydrogen atom or hydroxy group from a cyclodextrin derivative. The cyclodextrin derivative has such a structure that the hydrogen atom of at least one hydroxy group of a cyclodextrin is replaced with a group selected from the group consisting of a hydrocarbon group, an acyl group, and —CONHR wherein R represents a methyl group or an ethyl group.
