Abstract
The present invention provides a material combining properties possessed by crosslinked polymers with stretchability or viscoelasticity, and the producing method thereof. The present invention provides a material comprises a polyrotaxane and a polymer, wherein the polyrotaxane comprises a cyclic molecule, a linear molecule which is included in cavities of the cyclic molecules in a skewered manner, and a capping group which is located at each end of the linear molecule to prevent the dissociation of the cyclic molecules, and the polyrotaxane is bound to a part of or all of the polymer through the cyclic molecule.
Claims28
A material comprising a polyrotaxane and a polymer other than a polyrotaxane, wherein the polyrotaxane comprises a cyclic molecule, a linear molecule which is included in cavities of the cyclic molecule(s) in a skewered manner, and a capping group which is located at each end of the linear molecule to prevent the dissociation of the cyclic molecule(s), and wherein a part of the polyrotaxane and the polymer is bound to each other through the cyclic molecule.
A method for preparing a material which comprises polyrotaxane and a polymer other than a polyrotaxane comprising the steps of:
- a) mixing the polymer and the polyrotaxane which comprises a cyclic molecule, a linear molecule which is included in cavities of the cyclic molecules in a skewered manner, and a capping group which is located at each end of the linear molecule to prevent the dissociation of the cyclic molecules;
- b) physically and/or chemically crosslinking at least a part of the polymer;
- and
- c) binding the at least a part of the polymer and the polyrotaxane through the cyclic molecule(s).
A method for preparing a material which comprises polyrotaxane and a polymer other than a polyrotaxane comprising the steps of:
- a) mixing a monomer constructing the polymer and the polyrotaxane which comprises a cyclic molecule, a linear molecule which is included in cavities of the cyclic molecules in a skewered manner, and a capping group which is located at each end of the linear molecule to prevent the dissociation of the cyclic molecules;
- b) polymerizing the monomer to form the polymer;
- c) physically and/or chemically crosslinking at least a part of the polymer;
- and
- d) binding the at least part of the polymer and the polyrotaxane through the cyclic molecule(s).
