Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A macromolecular material comprising a first macromolecular compound having a ring host group, and a second macromolecular compound free of the host group, the host groups being covalently bonded to a side chain of the first macromolecular compound, the second macromolecular compound penetrating through the ring of the host group in a skewering manner, and neither end of the second macromolecular compound having a blocking group. 2. The macromolecular material according to claim 1 , wherein the host group is a monovalent group formed by removing one hydrogen atom or hydroxy group from a cyclodextrin derivative, and the cyclodextrin derivative has a structure formed such that a hydrogen atom of at least one hydroxy group contained in a cyclodextrin is replaced with at least one 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. 3. A method for producing a macromolecular material, comprising polymerizing a polymerizable monomer in the presence of a first macromolecular compound having a ring host group, the host groups being covalently bonded to a side chain of the first macromolecular compound, the macromolecular material comprising the first macromolecular compound, and a second macromolecular compound free of the host group, the second macromolecular compound penetrating through the ring of the host group in a skewering manner. 4. The method for producing the macromolecular material according to claim 3 , wherein the polymerizable monomer penetrates through the ring of the host group in a skewering manner while being polymerized. 5. A method for producing the macromolecular material according to claim 1 , comprising mixing the first macromolecular compound and the second macromolecular compound, thereby allowing the second macromolecular compound to penetrate through the ring of the host group in a skewering manner. 6. A method for producing a macromolecular material, comprising polymerizing a polymerizable monomer in the presence of a first macromolecular compound having a ring host group, the macromolecular material comprising the first macromolecular compound, and a second macromolecular compound free of the host group, the second macromolecular compound penetrating through the ring of the host group in a skewering manner, the host group being a monovalent group formed by removing one hydrogen atom or hydroxy group from a cyclodextrin derivative, and the cyclodextrin derivative having a structure formed such that a hydrogen atom of at least one hydroxy group contained in a cyclodextrin is replaced with at least one 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. 7. The method for producing the macromolecular material according to claim 6 , wherein the polymerizable monomer penetrates through the ring of the host group in a skewering manner while being polymerized.
