Abstract
Provided are a macromolecular material that exhibits high toughness and self-healing properties, and that can be produced by a simple process, as well as a method for producing the material. The macromolecular material contains a crosslinked polymer crosslinked by the interaction between a host group and a guest group. The crosslinked polymer contains a repeating structural unit represented by the following formula (1a) and a repeating structural unit represented by the following formula (2a).
Claims7
A macromolecular material comprising a crosslinked polymer that is crosslinked by interaction between a host group and a guest group, the host group being a monovalent group,
- the host group being at least one member selected from the group consisting of α-cyclodextrin, β-cyclodextrin, and γ-cyclodextrin,
- the crosslinked polymer comprising a repeating structural unit represented by the following formula (1a) and a repeating structural unit represented by the following formula (2a):
- wherein Ra represents hydrogen or methyl, RH represents the host group, and R1 represents a divalent group formed by removing one hydrogen atom from a monovalent group selected from the group consisting of hydroxyl, thiol, alkoxy optionally having at least one substituent, thioalkoxy optionally having at least one substituent, alkyl optionally having at least one substituent, amino optionally having one substituent, amide optionally having one substituent, aldehyde, and carboxyl;
