    Abstract: Provided are a macromolecular material comprising two or more types of polymers, which are less likely to be separated, and having excellent mechanical properties, a method for producing the same, and a macromolecular compatibilizing agent. The macromolecular material according to the present invention comprises a first macromolecular compound having a ring host group, and a second macromolecular compound free of the host group, and the second macromolecular compound penetrates through the ring of the host group in a skewering manner. The method for producing the macromolecular material according to the present invention comprises polymerizing a polymerizable monomer in the presence of the first macromolecular compound. The macromolecular compatibilizing agent according to the present invention comprises a macromolecular compound having a ring host group.

    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: The present invention provides a joined body with no risk of detachment from the joining surface without using an adhesive, and a method for producing the joined body. The present invention also provides a reversible joined body that enables control of joining and dissociation, and a method for producing the reversible joined body. In the joined body, a chemical bond is formed between two or more same or different solid-state materials at their contact interfaces by a chemical reaction.

    IPC: C08G83/00

    Abstract: Provided is a macromolecular material that has self-healing properties, excellent stretchability, and a high degree of freedom in the design of stretchability, strength, and hardness, and that can be produced by a simple method; and also provided is a method for producing the same. The macromolecular material of the present invention comprises a polymer having a host group and a guest group. The host group is a monovalent group formed by removing one hydrogen atom or hydroxy group from a cyclodextrin derivative. The polymer is a polymer of a monomer mixture containing a host group-containing polymerizable monomer, a guest group-containing polymerizable monomer, and a third polymerizable monomer, and the third polymerizable monomer contains a (meth)acrylic ester compound. The host group-containing polymerizable monomer and the guest group-containing polymerizable monomer have a property of being dissolved in the third polymerizable monomer.
